Green Filter Sport Air Filter | Renault Megane 4 RS 1.8

The risks of a clogged factory paper filter: what your Megane 4 RS loses during acceleration

The 1.8 Turbo TCe engine powering the Renault Megane 4 RS demands a massive supply of fresh air to quickly build maximum boost pressure. The original disposable paper filter, due to its dense and rapidly dust-clogged structure, creates significant restriction in the intake tract. Keeping a choked stock filter results in increased turbo lag, sluggish throttle response, and higher fuel consumption.

Failing to replace a dirty or worn paper filter also exposes your turbo's compressor wheel to fine dust particle ingress, which is especially damaging during hard driving or track days. By equipping your sports car with this Green Filter sport air filter, you remove intake restriction: you restore instant turbo spool, enhance the 1.8 TCe engine's intake induction sound, and stop buying disposable paper filters at every oil service.

Crafted from high-permeability oiled multi-layer cotton, this sport air filter guarantees up to 40% more airflow compared to the original paper filter while ensuring total engine protection against impurities.

Engineered to last the lifetime of your car, this washable cotton air filter for Megane 4 RS is easily cleaned and re-oiled using official Green Filter maintenance kits.
