Hey everyone I've had my Stillen intake for about a year and 12k miles....should I clean it yet? How actually do I do that? I lost my info...The actual filter is K&N....

 

pick up a K&N recharge kit..the instruction are inside. good luck.

BTW good time to clean it if you don't see that nice pink/off pink color anymore.

 

damn...then you should have cleaned yours a loooooooooooong time ago

 

joo forgot where i live? i drive down the block it's dirty again.

 

i forgot

 

general rule of thumb is u gotta clean it out once a year

 

remember also, that a dirty K&N filter will filter better than a clean K&N and allow for better flow.
Clean it anyway

 

Its fine.

You don't have to clean it until you get a dirt buildup. K&N says the filter can go 50K-100K miles without cleaning. It also says just because the red goes away, doens't mean the oil is no longer there.


...but being **** with my cars I do clean them about once a year.

 

Thanks everyone, I really appreciate it!!!

 

K&N says you don't have to clean for 50,000 miles. That's a stretch, but that's how they validate their 1 million mile warranty...i.e. the filter can last 20 cleanings. I clean mine every 10k miles or so, figure that will make the filter last 200,000 miles, much longer than the car will last.

 

How's a dirty air filter gonna have better airflow than a clean one? Dirty means dust and crap has wedged it's way into the fibers and blocked possible air-travel paths. Someone please explain this to me. Blocking air flow increases the vacuum behind the filter too, which increases the chances that dust is going to get sucked through the filter and into the intake tract. Or am I completely stupid?

 

The dirt particles collected on the surface of a K&N element have very little effect on air flow because there are no small holes to clog. Particles are stopped by layers of crisscrossed cotton fibers and held in suspension by the oil. As the filter begins to collect debris, an additional form of filter action begins to take place because air must first pass through the dirt particles trapped on the surface. That means the filtration efficiency of a K&N element actually increase as the filter collects dirt. Tests have shown a K&N E-1500 filter will flow 60 percent of its maximum flow capacity after 50,000 miles of street use. And, considering a new K&N flows at least 50% more than a comparable paper element, that same filter will provide all of the air the engine needs even after 50,000 miles.

Sweet, thanks.
