K&N 33-5029 Air Filter Product Reviews

Amazing I installed this in my car and it feels sharper faster and the engine feels loose or free compared to before. It seems to rev much more freely, also I have noticed as other people have said that the fuel consumption is much better.

The vehicle that the filter is going in hasn't been built yet but I can give it 5 stars because I have used K&N filters for years and I know without a doubt that the quality and performance will be as advertised.

Thanks. I think I like product didn't noticed to much acceleration difference but its to cold to full enjoy Mustang. Fuel economy seems to be improved. Foto before and after installed filter added...11 l/100 vs 14 l/ 100 same road, same speed 350 km long :). Funny thing is when I tried to buy this filter here in Poland your local reseller (Intercars) told me first I need to wait 30 days....and after that that its not available at all. You shipped it to my door in 7 days.

I love my new air filter for my s550 Mustang. Gives a little better acceleration and an extra growl to the engine.
