Ε KODA Octavia A5 - one of the most popular models of the Czech brand, known for its reliability and practicality. However, over time, even such a car develops problems with body elements, especially with the wings. Owners often encounter corrosion, dents or scratches on standard metal parts, forcing them to look for alternatives. Plastic fenders are becoming an increasingly popular solution due to their lightness, rust resistance and affordable price.
But are they really that good in practice? In this article we will look at all the nuances: from choosing high-quality plastic fenders to their installation and operation. You'll learn which brands are trustworthy, how to avoid installation mistakes, and how plastic differs from metal in the long term. And also - exclusive tips on painting and care that will extend the life of your new parts.
Plastic vs metal fenders: which is better for Octavia A5?
The main question that concerns owners is whether it is worth replacing the original metal fenders with plastic ones. Let's compare the key characteristics:
| Parameter | Metal wings | Plastic wings |
|---|---|---|
| Weight | ~8β12 kg (depending on model) | ~3β5 kg (2β3 times lighter) |
| Corrosion | Susceptible to rust, especially in chipped areas | Do not rust, but can crack from impacts |
| Maintainability | Can be straightened, welded, putty | Cracks are repaired by welding plastic or replacing |
| Price | From 15,000 rubles for the original (used is cheaper) | From 6,000 rubles for a high-quality analogue |
| Installation | Requires welding, more difficult to install | Mounted with bolts/rivets, easier to replace |
The main advantage of plastic - no corrosion. This is critical for Octavia A5, where the wings often suffer from reagents and mechanical damage. However, plastic is less resistant to strong impacts: instead of making a dent, it may crack. It is also important to consider that not all plastic fenders are suitable for standard painting β some require a special primer.
One more nuance: plastic can "play" at high temperatures (for example, in the heat or after washing with hot water). This is not critical, but can affect the gaps between body parts. Metal is more stable in this regard.
β οΈ Attention: Cheap plastic fenders are often made from recycled materials, which lose strength over time. Focus on brands with a warranty of at least 2 years.
Top 5 manufacturers of plastic fenders for Octavia A5
The market offers dozens of options, but not all are trustworthy. We analyzed reviews from owners and experts to create a rating of trusted brands:
- π₯ Heko (Germany) - premium segment, ideal geometry, suitable for painting without modifications. Price: from 12,000 rubles.
- π₯ Febi Bilstein (Germany) - optimal price/quality ratio, resistant to UV radiation. Price: 8,000β10,000 rubles.
- π₯ Ruville (Germany) - a budget alternative with good reviews, but requires adjustment. Price: 6,000β8,000 rubles.
- πΉ Polcar (Poland) - popular in Russia, but there are defective copies (check before buying!). Price: 5,000β7,000 rubles.
- πΉ AvtoVAZkomplekt (Russia) is the most budget option, but the quality of the plastic is often poor. Price: from 4,000 rubles.
Selection advice: Pay attention to plastic marking. Quality parts are made from ABS plastic or polypropylene (PP) with reinforcement. Avoid wings from PVC - they are fragile and do not tolerate temperature changes well.
Also check the package: the kit must contain all fasteners (bolts, rivets, seals). If you donβt have them, youβll have to buy them separately, which will increase the final cost.

Step-by-step instructions for installing plastic wings
Install plastic fenders on Octavia A5 You can do it yourself if you have experience working with the body. Otherwise, it is better to contact the service - installation errors can lead to distortions or leaks.
To work you will need:
- π§ Set of sockets and keys (sizes: 10, 13, 17 mm).
- π¨ Drill with a metal drill (if you need to make new holes).
- 𧲠Riveter (for fastening plastic to metal).
- π¨ Body sealant (eg Teroson or 3M).
- π οΈ Plastic clips (usually included).
Procedure:
- Remove the old fender by unscrewing the bolts securing it to the body and bumper. Be careful with
fog light wiring(if they are installed). - Clean the mounting area from rust and old sealant. Treat if necessary
anticorrosive. - Try on the new wing and mark the locations for additional holes (if they do not match the old ones).
- Secure the wing with bolts and rivets, starting from the top. Do not fully tighten the fasteners until all gaps are aligned.
- Apply sealant to the joints with the body and bumper. Use masking tapeso as not to stain the paint.
- Adjust the gaps (optimal - 3-5 mm) and finally tighten the fasteners.
βοΈ Preparing to install the wing
The hardest part is combination with bumper. On Octavia A5 Often there are problems with clearance near the wheel arch. If the fender moves up or down, try loosening the bumper and adjusting its position.
β οΈ Attention: If you are installing a wing with fog lights, do not forget to transfer the connectors and check their functionality before final assembly. A common mistake is pinching the wiring, which leads to a short circuit.
Painting plastic wings: technology and nuances
Painting plastic is more difficult than metal; special preparation is required. If you skip even one step, the paint may peel off or go blistering in a few months.
Step-by-step technology:
- Degreasing. Use antisilicone or
white spirit. Don't use acetone - it can corrode the plastic. - Primer. Apply adhesive primer (for example, PPG DP40 or Sikkens Autoclear). It ensures the paint adheres to the plastic.
- Putty. If there are defects, use putty for plastic (for example, Novol Plastic). Regular car putty will not work!
- Painting. Apply paint in 2-3 layers with intermediate drying. For Octavia A5 it is important to choose a shade that matches the body color code (indicated in
nameplate on the door pillar). - Varnish. A protective layer of varnish is required - it prevents the paint from fading.
A critical nuance: plastic has a different coefficient of thermal expansion than metal. If you do not use an adhesive primer, the paint will crack at the first temperature change.
Cost of painting in the service: from 5,000 rubles per wing (including materials). If you paint it yourself, the budget will be ~2,000β3,000 rubles, but without experience, the risk of ruining the part is high.
What happens if you paint plastic without primer?
Without an adhesive primer, the paint will lie unevenly and begin to peel off after 3β6 months. This is especially noticeable on Octavia A5 with dark body colors (for example, Deep Black or Brilliant Silver), where the defects are obvious.
Common problems after installation and how to avoid them
Even with proper installation, problems can arise with plastic fenders. Here are the most common of them and solutions:
- π Creaks and knocks. They arise due to insufficient fixation or lack of seals. Solution: pave poroisolon tapes between the fender and the body.
- π§ Water leaks. If the sealant is applied poorly, moisture will enter the interior through the mounting holes. Solution: Re-seal using seam sealant.
- π₯ Heat deformation. Plastic may βdistressβ after washing with hot water or in hot weather. Solution: avoid temperatures above +60Β°C, park in the shade.
- π¨ Paint peeling. Most often, the fault lies with poor surface preparation. Solution: clean the defective area and repaint with primer.
Another typical problem is color mismatch new wing with old body. Even if you select the paint according to the code, over time the original enamel will fade. To avoid this, order tinting to match existing color in a specialized workshop.
If after installation the wing "walks" when pressed, check:
- Are all bolts and rivets tight?
- Are the mounting βearsβ on the body deformed?
- Is there any play at the junction with the bumper?
Before purchasing a wing, check its geometry by attaching it to the original one (if it has not yet been removed). Even branded manufacturers have batches with casting defects.
Caring for plastic wings: how to extend their service life
Plastic is less demanding than metal, but also requires care. Basic rules:
- π§Ό Washing. Use contactless shampoos (for example, Karcher or Sonax). Hard brushes and abrasives scratch the surface.
- π‘οΈ Protection. Apply ceramic coating or wax - this will prevent paint fading and microcracks.
- π Winter operation. After traveling with reagents, rinse the wings with water. Salts corrode not only metal, but also plastic.
- π§ Repair of chips. Repair even minor damage pencil for plastic (for example, Fix It Pro). This will prevent cracks from spreading.
What not to do:
- β Wash your wings
gasolineorsolventsβ they destroy the structure of the plastic. - β Park close to heat sources (such as industrial furnaces).
- β Use polishes with abrasives β they erase the protective layer of paint.
The average service life of plastic wings with proper care is 5β7 years. After this, the plastic begins to lose strength, especially if the car is operated in a harsh climate.
Regular plastic processing UV protective compounds (once every 6 months) extends the life of the part by 2β3 years.

FAQ: Answers to frequently asked questions
Is it possible to install plastic fenders on Octavia A5 with a diesel engine?
Yes, engine type does not affect wing compatibility. The main thing is to choose a part for your body modification (sedan or station wagon). Please note that on diesel versions, additional fasteners are sometimes installed for particulate filterwhich may interfere with installation.
Which plastic is better: ABS or polypropylene (PP)?
ABS plastic stronger and more shock-resistant, but less resistant to low temperatures (may become brittle in the cold). Polypropylene (PP) more elastic and lighter, but less rigid. For Octavia A5 optimal reinforced polypropylene - it combines the advantages of both materials.
Do plastic fenders need to be treated with anti-corrosion agent?
No, anticorrosive material is not needed for plastic - it does not rust. However, it is recommended to process joints with metal body (for example, under the fender) to prevent body corrosion. Use anti-gravel mastics rubber based.
Is it possible to drive with a cracked plastic fender?
If the crack is small (up to 5 cm) and does not affect the fasteners, then yes. But if the damage is severe, the wing may break off on the move, especially at high speed. Temporary solution - fix the crack fiberglass and epoxy resin, but it is better to replace the part.
Do plastic fenders affect MTPL insurance?
No, replacing fenders with plastic ones does not require changes to the policy, as this is not considered a change in the design of the car. However, if you changed the shape wings (for example, extended arches were installed), this may lead to problems when registering an accident.
