Improved engine breathing
Installed right away. Perfect fit. Much thinner than the oem and I think this adds to the air flow capability. I installed in my BMW with Turbo and made an immediate impact. Turbo lag in Sport mode that I was experiencing is gone. Not sure about more overall HP gain but I’m very happy with the result I got.

Makes complete sense for your wallet and the car's sound
I purchased this K&N air filter for my 2009 Lexus gs350 along with the other K&N air filters for a 2018 BMW 330i and a 2015 Cadillac SRX. All of these filters were between $50 and $60 for the filter which should las the lifetimes of the cars with a little cleaning. Changing the air filter couldn't have been easier and I will no longer have to purchase a $10-$15 air filter every other oil change. So far there have been no issues and because of that I am happy with my purchases. There has been no noticeable increase in MPG but the filter does seem to give the exhaust a better sound. It sounds like the cars are breathing better. That may be just my perception but I did notice a better sound with new K&N filters.

Worth it!!!
I was initially hesitant. I took the risk so you did not have to. The filter does work as the manufacturer states. Not too sure about the horse power, but there is greater oxygen flow to my engine and some more sound is possible. So far good results. I've only done 5000 miles. I will do an update after 10,000 miles.

It's K&N!
This filter like many other K&N filters I have owned are easy to install and can be cleaned. As for the performance of the filter is really up to the person. I did not really feel the performance factor. Installed on a BMW 340i and no issues with CEL or engine engine management. Quick upgrade to a paper filter. Only gave it four stars for the fact it was dripping in oil. The box was even damaged with oil even though the filter was in a sealed bag. Just made sure to clean up any excess oil from the filter by using a towel to absorb the excess. Keeps the oil from getting in to the MAF sensor and causing issues.
