Reviews of K&N parts For Business

That is why I always buy a k&n filter where can just use a wrench.

Wanted turbo noises but couldn\u2019t justify $200-$300. Parts : 3 inch OD - 3 inch OD pipe. K&N 3 inch filter, APR SAI Filter. Drilled a vaccum tap into pipe. Sounds really nice. I know not much gain but sounds good lol.

I put a K&N nut topped filter on it and never had to do that again!

So far K&N is on track to hit 10k before I change my oil again.

I watched a YouTube video and got a reusable air filter from K&N

Engine carbon cause the dirty looking oil no filter can get rid of the carbon color and I don't wait 5000 miles I change every month but put on 500 km every week highway also your oils detergents could have cleaned some crap from engine I would do a change sooner myself am switching to Pennzoil ultra platinum 5w 30 and k&n gold for maximum flow rate/ oil pressure and 30 micron rating (70 micron is human hair) year round I've got about 335,000 km on Buick Lucerne 3800 series and aiming for 500,000 I used wix XP for years bought bulk from rockauto and got carbon black every change including my ram1500 only 150,000 km highway

I put one on my 08 , it's good but it throws check engine lights on me.

The k&n gets you nothing except for letting a lot of dirt through if you don’t oil it regularly.

K&N air filter is rated as the worst thing you can put on your vehicle. We tested different 'cold' air intakes when I went to Nascar Tech and K&N will take away around 8 horsepower.

Previously used the k&n one and it always leaked. After 3 filters, i switched
