How bad can K&N red filter oil damage the engine if a little bit gets inside the intake. I oiled it, then put it in the car, then had to leave right away and my engine made some funny sounds for like an hour but i'm not sure if I did any damage of any kind.

 

It'll burn along w/the fuel.

The problem would be w/it coating the MAF wires. Clean them off.

 

....must be why my car idles wierd.....as long as the oil isn't too sh!tty fpr the engine. Thanks...i feel better now.....

 

the first thing to do is not put so much oil on the filter. also, there is a bulletin that could void the warranty based off of excessive oil on after market air filters like k&n. there has been problems with damage to the iat sensor, etc and it may not be covered under warranty if you soak the air filter with too much oil.

 

Too much oil sounds like the problem
