k & n filter questions

Recommended Posts

I have an 08 dodge cummins that has a cold air intake with a k &n filter. I notice that the "filter minder" is always reading that the filter is dirty. I was told these filters are supposed to be good for 100k with minimal maintenance. This filter has about 20k on it, all good highway (minimal gravel) miles. Can I just blow it out? What else can/should i do? Should I clean it and not oil it? Any help/ideas is appreciated.

K&N filters need to be cleaned about every 10K purchase a cleaning kit it contains cleaner and a oil kit should cost about $15 don't you air on your filter it will just push the dirt into areas it will be hard to clean or it will blow a large hole in it. Use 2 five gallon buckets of hot water, tap filter to get loose dirt off than spray cleaner onto filter let soak rinse in water repeat if necessary then rinse again in clean water let air dry once dry liberally reoil repete every 10-15,000 miles

I would throw it away and go stock, unless you are racing the truck or using it for a swamp buggy.

Some very in depth testing NOT done by an air filter manufacturer- air filter test link

These are pretty much the standard feelings for mechanics. Throw them away and use stock. They do more damage to engines, turbos, and MAF sensors then anything.
