I have used this air filter on my 1995 Lexus SC400 without any ill effects (this is in response to the other review). I use K&N filters on all three of my vehicles and have noticed some fuel economy improvement. I have never done any performance testing. K&N air filters will pay for themselves in the long run and keep throwaway air filters out of our landfills. These are good products and I have used K&N filters for over a decade.

Made a considerable difference when moved from standard filer to KN panel filter. Was quite shocked how much more it gives and sounds from stock blow off are now pretty loud - BPU Supra does not require induction kit it is a waste of money - drop in panel filter is a the best option. Had it on many of my previous cars always happy.
