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.

I replaced the stock filter with K&N 33-2539 a month ago for my Citroen Xantia 3.0i V6 194 hp, myself.  Since then I have found the diffrence in a way that never happened before. It roars and hops. Also, acceleration at higher speed (140-180 kph) is fantastic, really. Worth investing for driving pleasure.  No other information has been collected yet.

Congratulations on a fantastic product. I own a Citroen Xantia HDI 2ltr diesel, now semi retired, after 51 yrs on the spanners, also I tow a caravan 15ft. I am really pleased with my K&N filter, I fact I have just purchased a Daihatsu Sirion 1ltr petrol car ,so am going to put a filter in this one as well, as petrol in the Uk is £1/04 a ltr, so one has to get the most out of your petrol as possible.
