33 2129 High Performance Replacement Filter

Excellent product, fast shipping. I swear by these filters for both added power and increased fuel efficiency. I purchased this one for my ’03 Suburban, and have utilized others in an ’07 Altima, a ’99 BMW 540i and a supercharged ’91 Maxima. All performed flawlessly.

I purchased this item for around $20 on a exceptional and glad I did. I’m not out changing air filters all the time and this one seems to have given me in regards to 1/2 mpg better efficacy in my civic. I can’t comment on HP because I don’t actually feel an increases

I obtained this and did a simple install in my 2007 Chevy Silverado 5.3L, my onboard computer shows that I now get an extra 2 miles per gallon and I noticed a slight increse in torque.

Saved a little money on gas not much but a little, the throttle response is very noticeable.

The introductory step in the instructions will have to be on the outside of the box and ought to say, “Open the package and remove the air filter. See? It’s the rectify size!”

If you’re like me, you’ll remove the old filter and realize there’s no way the box dimensions are the same as the OEM filter. I nearly returned it, but the K&N internet internetlocation said it fit, so I opened it up and tried again. Thanks to the packaging, the actual filter is in regards to half the size of the box.

Anyway, this fits my 2007 Tahoe and 2009 Silverado. Somewhat tight squeeze to get the box cover back on, but otherwise swell product, and long lasting.

this is not my 1st K&N air filter , so with my experence i highly commend it . my 08 sierra went from becoming 14 .1 mpg to 15.3 in town , i have not been on the road yet . it will rapidly recompense for itself !

I love these things. They last forever, give more air to the engine (ie better mileage or more power) AND clean the air better as well. Plus, they compensate for themselves after with regards to the third time you clean/reuse them vice buying paper filters (which means the rest of the car’s life is gravy).

You need to buy a recharge kit as well which costs ~$10 and is good for 20-ish cleanings. It doesn’t have to be right away as the filter comes ready to go for the primary use cycle.

I clean mine about every 25,000 miles or whether or not I detect a drop in gas mileage.

I put them in all the vehicles I maintain; this is my ~7th one in 15 years. I will mechanically put one of these in every car I buy. I wish my furnace had a filter this good!

The only vehicle I ever had an issue with was a 2000 Subaru Forester S 2.5 Automatic, it did not seem to carry out better with the filter and it necessitated cleaning constantly.

Dont forget to put the included decal on the filter housing so the filter does not get thrown away for the duration of a dealer sevice package (although if a mechanic threw one of these away instead of giving it back to you when you retrieved your car, it would be prima-facie proof that they were incompetent and you should stop going there.)

Recieved in good order and promptly. I am still trying to determine the precise mileage improvement, about in regards to mpg. Noticed the improved acceleration immediatly. My factory filter was definitly restricting air flow.

Filter fit nicely, not much increase on mpg however underneath load seems to have more acceleration, main reason for changing to filter was the fact that you can clean and reinstall which with fuel costs and the push for doing more maintenance such as changing the air filter more often times the filter will remunerate for itself quickly, I also got the cleaning kit on my primary buy

I lately purchased a new 2007 Chevy Silverado. A friend told me about K&N filters and suggested I get one for my new truck. I did such a great deal of research on the Internet, at the K&N web site and other places, and decisive to go for it and ordered the filter from Amazon.

Chevy trucks are known to hesitate just a fraction of a second when you hit the accelerator. My new truck was no exception, but as I have driven Chevy trucks for 20 years I was employed to its Immediately after installing the K&N filter, to my amazement, the hesitation was gone. There was also a slight but noticeable increase in power.

I’m very impressed with the performance increases I have seen just from replacing the factory air filter with this superior product.
