hey everyone i just got my HKS downpipe a few minutes ago, wont be able to install it for a while though. However i've got a quick question about a little threaded hole on the top of the dp, right on the top of the "cobra head" if you will does this connect to anything or should i be trying to find somethign to plug it with?
thanks

 

i believe that is for your O2 sensor. Correct me if im wrong.

 

yeah, you will need that for your o2 sensor

 

NO, you guys are terrible...

that is for the fuel line when using your afterburner!

 

o thank god i thought it might have been for something actually useful
thanks thouhg guys

 

order some header wrap and wrap that bad boy before you install it. helps keep it cooler under hood.

 

hmmmmm
i crammed a spark plug in mine
