Besides the fact that this filter will need to be cleaned maybe only three times before my 1991 V6 Toyota 4x4 SR5 croaks of old age, which I hope is 15 years hence, it boosted fuel consumption in my pickup by a whopping third. How do I know? Used to be I always filled up on the second trip to town. Now it is on the third trip to town.

I recently bought this filter for my 1990 4 Runner rock crawler and immediately felt a difference in the responsiveness of the car. With the stock one, it felt like I had it floored before it would actually move. The K&N filter just seems like it is flowing better and allowing the engine to breath. Unfortunately I trashed the filter while having a little fun in the mud but was able to clean in out and reuse it. Definitely buying a back up one for mud trips. Over all good buy.
