Air Filter Cleaning Question

[yobiebs]

Hey guys,

I tried searching old threads for this info, cuz I'm sure it's come up before, but I couldn't find anything.

Could someone please let me know what the recommended frequency for cleaning the air filter is? I have the K&N Air raid filter, and realized that I haven't cleaned it since I got it a few months ago.

Any help would be appreciated. Thanks!

Biebs,

There's no set time to clean your K&N or for that matter any cleanable filter. Used to be a rule of thumb that if you take your filter out and hold it up to daylight, and you could still see thru it, then it didn't need cleaning. Unless you live in a really dusty area, you can go for quite awhile before cleaning. Personally, all three of my cars and all the cars I've owned had a K&N of one sort or another. I use K&N's own cleaner and oil and clean each one around about 20,000 miles, but I do inspect it every once in awhile before that to make sure it's still clean.

I think K&N say 40 or 50K ore something like that. They don't recommend it too often.

20. How do I know when to clean the filter?

The general rule of thumb is that the filter needs to be cleaned when the dirt build up gets as thick as the wire mesh. The usual interval is 30,000 - 50,000 miles depending on driving conditions. We recommend that you check your filter about once a year in normal usage.

Search engines are COOL!

GTSTEVE, and that is about right. I clean mine once per year weather it needs it or not!! LOL!!

Just FYI about...

Service Life

A K&N Filtercharger can be washed up to 25 times before it is considered no longer serviceable. Even though the filter may not show outward signs of deterioration, it should be replaced after 25 washings. Excessive washings will deplete the tiny cotton hairs that crisscross the openings. The resulting damage will allow tiny dust particles to pass through.
