Hey guys the other day when I was going to install my KN Intake when I opened the decklid I found my oil cap loose almost falling off and I saw oil on the bottom of the decklid. Then today after I went out I came home to check on my intake to make sure things were tight I noticed the oil cap again came loose. Ive always noticed this cap doesnt lock or does it. Do I have a bad cap should it click tight?

I was also wondering if this could cause a MAF problem with these KNs. The oil hose is RIGHT next to the filter. Let me know what you guys think thanks

 

should not come loose like that.... loose cap will effect lose of vacuum, rough idle...

 

Make sure the O ring is present inside the cap and not twisted or missing. That firms it up when tightening.

 

You should not use a KN if you don't want to loose power, put the stock filter.

 

That's a pretty strong and uninformed claim, sir...

 

I got a friend, and it works at bmw service, he told me .. KN = 0

What is the advantage to put o K&N intake ? How many people from US put that filter on they cars ? it's something popular there ?

 

There are several other threads that discuss this topic, feel free to research them.

 

Isn't the oil cap still loose????
