Review: slight performance increase - 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.
Review: K&N is the best and only air filter you will ever need on any engine. - 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.
