Smoother performance.

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.
