Customer Feedback

My SAAB 9000 AERO Is twenty years old now and as sprightly as ever. I have used a K&N filter during all that time, buying new ones occasionally. The performance difference is pronounced... and fun!

Fitted a K&N E-9060 in my SAAB 9000 Aero - I have 12 years automotive tuning experience, I don't use any other filters. K&N has been in this game for a long time, with good reason - the products work, they are tested, guaranteed and best of all, sensibly priced.

Great filters, great performance. Thanks!

Works good on my Saab with the Vortec 4200 straight six. I feel like it would work alot better with the whole intake kit, filter and the duct work. I got a little more power but that air box is very restrictive.
