Not the first time that I use your products ( Volvo 460 & Citroen BX with carburators / K&N - 56-1651,Renault Clio 1.2 / K&N RX extreme series ), and now this one in Fiat 500L with 1.4 engine. All are great, I hope you'll make oil and fuel filters to for my Fiat. Sorry on my english, whish you all the best.

Excellent performance achieved after replacing my old paper air filter. Now my Peugeot runs more efficiently and I am helping the planet by not polluting it with old used air filters. Thanks for this super product!

I installed a K &N panel filter in my Peugeot 306 HDI. The mpg has increased from 43 to 47 over a brand new paper filter. The filter will pay for itself in 5 tanks of fuel at £1.40 a litre! Fantastic product.
