I have not had not any problems with them and I have always tried to use them. I've used them in my mark Porsche and my Mercedes now, and my Volkswagen turbo diesel I had, and it was perfect. It is nice to know the product works great and that it does what it says it will do. When I put it on my Porche, it was really fun to drive.

Great filter for my 2015 Chevrolet Trax 1.4L Turbo. Good sound upgrade and throttle response increase. Really helps your turbo breath in all ranges of rpm. Can't wait for K&N to release a cold air intake kit/upgrade. I check the website every week.
