2 or 3 whp

and the best way to know when you need to change the filter... well, honestly, just look at it. some people need to clean it every few months, whereas some clean it once a year or less. it depends on how dusty the area you drive in is, etc...

 

Yeah, just look at it and clean if necessary. You would probably be fine cleaning it once or twice a year.

 

cool thanks ... one more question i was thinking about how its set-up and i remeberd i have to connect one hose to the ..(i forgot its called valve cover?) part with the spark plugs whats the purpose of that hose? does anything go through there? or can i cap that off and put abreather on it .. i htink i heard somthing about that? or is that hose manditory

 

You can do either. It is just the vacum line. I am using the hose with the same exact intake, but it is just preference.

 

whats the vacume line do do you think it taek some of the air from the intake.. or does oil leak in from it?

 

Hence the "vacumm" line. No oil runs through it, just air.

 

i found a pic with what im talking about juss to make sure now this isnt my car i juss found this pic on google... (shHh) but this is the line im talking about.. can i take this off cap off the intake and put a cap on the cover or should i put a breather or juss leave it? is it manditory?

 

1.
just leave the hose as it's supposed to be connected, like in the picture.

that is your valve cover breather hose........

2.
look at the filter every 3 oil changes, or take into account the amount of dusty conditions you are in on a daily basis and adjust accordingly. When cleaning your K&N ... remember to tap it all around first to get all the large particles off, then only use a low pressure hose from the inside of the filter with water spraying to the outside.....never outside to inside......i prefer the hose and bucket technique.....

 

Buy a K&N filter cleaning kit, the one with detergent and oil included.

 

really sound great .. how much do they cost..?
