5 Star Review
I've used K&N's before. Saves a lot of money on buying new filters, especially if you plan on keeping your car for a long time. I bought these for my 2014 Nismo 370Z. Honestly, I wasn't expecting anything from their entry level filters other than saving money in the long run. Also, I wasn't expecting to add any serious horsepower - that's what the other models they have are for. But I did immediately notice about 1-1.5 miles more per gallon on my car. I had been keeping track of my gas consumption before I bought these filters to see if they made a difference. Turns out they did! Although it doesn't sound like much, it still comes out to potentially 20 more miles per tank (depending on how I drive). Savings are savings, so I'm pretty happy. Plus, since you only have to use the recharge kits to clean the filters, you absolutely save on money in the long run. I continue to be a believer in K&N. I plan to upgrade to one of their better filters eventually once I start modifying my car a bit.
5 Star Review
I have had these filters in my Nissan 370Z for 3 years and I notice the little extra performance and nicer engine sound (even though it's only slight, I know my car and it's definitely an improvement). Never had any trouble with filtration quality. I can't speak highly enough of the customer service I've received using this website either.
350Z Air Filters
First class product. The filters were a drop-in replacement for the standard 350Z filters, and the improvement in performance is palpable. Clearly improved throttle response and added power!
