had it for a week and i already have improved gas mileage and the engine is breathing better. keep in mind this only includes one filter so you’d have to order another one for the VQ37VHR. perfect oem fitment and amazing quality.

I have had K&N in every car that I have owned. The best air cleaner out there. I have always liked how you can clean them let dry,re-oil and install back into the car. the cleaning kit is not too bad on price and you can find it at any auto store. Hold any air cleaner up to a light and look through it next to a K&N and you will see the difference! Its plan as day. Very easy to install on my new to me 2010 Infiniti g37 sedan. I had them both installed with warning stickers in less then 5 min. Worth the up front cost because i will never have to buy another air filter for this car again. My last daily driver has 250,000 miles on it. That car I,m passing down to my son. It still has the K&N air filter on it that I installed when it was new.That K&N air filter looks like new after I cleaned it,re-oiled and installed. I'm 42 now and will have this product in every car that I every own until I'm gone.

Great and awesome! Very tight fit so just be careful installing! The packaging and website tells you, you can wash these and rinse the filters for reusability! Worth the price for my Z to breathe!

After keeping track of my mpg for almost 10k miles on the K&N filters, I can honestly say they performed better than I was anticipating. I do 50% of my driving on busy but flowing country roads 55-65 mph with few to no complete stops. 35% congested City, and 15% highway. I'm averaging 1.9 mpg better with these filters installed. I can't speak to any horse power gains as I haven't put the car on a Dyno. Sometimes I think it might be a little peppier, most of the time I'm not sure.

K&N is a quality product. But definitely a tight fit for the G37! Push on the latches to get it to hook onto the airbox.

I put these in a 2009 G37x which requires two filters so be sure you're buying two if needed. Anyways at certain lower RPMs the car felt a little sluggish so I decided to check out the filters & they were cheap restrictive looking filters so I bought K&N put them in & went for a drive and I could feel the difference in acceleration and "get up" in the lower RPM range the throttle response improved I was actually surprised. They look much better quality & I could see how the air flow will improve just by comparing this filter to the one I got with the car. I would recommend, it's worth the money in the long run. Eventually I'll get a cold air intake but meanwhile this will do lol

I have a 2010 infiniti G37X and these drop right in. easy as can be. might be a little hard to close the tabs on the airbox after but a little extra mustard wont hurt and gets it back on tight. I don't notice too much power or sound but the convince of being able to just wash and re-oil these instead of buying new ones every 20k-40k miles is worth the money

I installed two of these K&N engine air filter in my 2018 Nissan 370Z. The car is so fast normally that I really can’t tell if it’s any faster with the K&N filters. However, I’ve been using K&N filters in my other vehicles (cars and motorcycles) for years without any problems and have experienced noticeably improved acceleration in some of those vehicles. The filters may be pricey but they are worth it. Once you buy one you never have to replace it - just clean and service the filter using the K&N filter service kit every 50,000 miles.

Got those for a 2015 370z car is stock as if new from mechanics point of view. After 6 to 8 weeks the car turned to have a huge acceleration lag and I believe the MAF’s need to be either cleaned or replaced. I would recommend to think 20 times before you jump into flushing OEM’s parts into good marketing after market ones.. Not happy with the results at all

No real difference in induction noise on the 370Z. However as these last the lifetime of my car I will save not putting cheap over priced ones at service intervals. Plus added bonus of engine bay bling K&N stickers. =)

Great quality! The K&N filter fits perfectly on Infiniti G25 and improves airflow and throttle response. Love it!

Fait bien le travail
