Reviews of K&N parts For Business

i have no other power mods, just a plain k&n drop in air filter and you can feel the power difference big time over stock. noticeably quicker.

I've had one for years and no issues. Just oil it correctly. Also, watch engineering explained video on it and it does add some power. Not much. And I don't have any mpg gains.

In my time of ownership I've been doing oil changes are 7500 miles per the book with a full synthetic mobil 1 and a K&N oil filter since we got it with 155,000 on the clock.

I would recommend a K&N cloth filter. They can be cleaned and re-oiled about every 50K miles. They never need to be replaced.

I run K&N's on my Harley and the blower on my SBC. No issues.

I’ve found them to be good

OEM. I order a bunch off of Rock Auto. Two of the K&Ns I've had leaked just the tiniest bit but enough to be annoying. Granted, I'm not on a stock turbo or stock by any means, so maybe that has something to do with it.

Besides the need for washing and re-conditioning, these filters also have the drawback that they were originally designed for increased airflow to the engine. For one, we don't have an engine to begin with. What we need is good cabin air. In this sense, the increased airflow is counterproductive as it lets more "stuff" through than regular filters. If you want the best cabin air, I would recommend a carbon-coated cabin filter. I have been using and have had no issues with air restriction, and I believe the air is better air compared with the other two vehicles in our family (but they are ICE vehicles, so who knows).

K&N is probably the most annoying with the rounded off nut they expect you to use to get the filter off. I'll never buy one of those again.

I had a Jeep with a K&N air filter with the "do not discard- permanent filter" stickers on the air box. I loaned it to a friend for a few months, and to thank me, she took it in to get the oil changed. They told her the air filter was oily and needed replaced, and she told them OK.
