Great Product
If you care about your car, K&N washable/reusable filters are an excellent add to your vehicle. I run these on all my vehicles (car, truck, motorcycles). They save a lot of money and perform very well!

Great Product, Not Applicable
I’m only giving K&N a 5 star because I know how great their products are. I’ve had it on my Infiniti G37, tuned BMW 335i, my 2nd gen Toyota Tacoma, and never had an issue. Recently traded in for a 4th gen Tacoma TRD hybrid and ordered the filter. After I installed it, I drove to pick up my fiancée from work and back home. Immediately I felt a loss of power and torque making it seem it needed more air and acceleration to get up to speed even in Sport mode. I just reinstalled the original Toyota air filter and it’s back to normal and torquey. Wish this filter would’ve been okay because now I have the K&N filter cleaner and oil sitting in the garage to not be used again after using K&N for so long lol. I’d put it on any other car but I don’t think it’s best on the new Tacoma unless it’s got the Overland Tailor Tune.

Performance and economy. First mod for every vehicle
I've purchased these filters for long time and in turbo cars is a must. I noticed great improvement is city driving mpg. Bought it for a nx200 back in 2018. Just got a Nx300Fsport and must say is just a day and night difference when using these filters.

Permanent filter
Love the permanent air filter for my 2025 Toyota Tacoma. Easy install and much more effective than the paper filter.

Can’t go wrong with the K&N brand
I’ve always used K&N engine air filters in all of my vehicles. Simply put, they are well made and super solid. Not sure if I notice any improved mpg’s on my car, but I definitely feel that it does help eliminate any type of engine hesitation/delay. Be sure to not over oil or oil on both sides of the filter as this runs the risk of damaging or throwing a code in the MAF sensor. K&N swears that this is scientifically impossible, but believe me, it happened when the dealer found out that the excess oil ran in/sucked into the MAF sensor... I’d give it a solid 5 stars if it wasn’t for Amazon price gouging from $45 back in December to $65 in January.
