Plog KR

How much about will a plog usually lower KR?. I know headers will lower it more but just looking at the simpler install of a plog. Thanks.
 


Ohh got it. My engine is stock except for a K&N CAI, i just did plugs and wires about 10,000 miles ago, always run 93 and still see about 5* of KR at WOT. Is that normal in a stock engine?
 


Okay thats good to hear, i guess lol. Now i'm just curious as to how much people have seen a PLOG lower KR.
 
According to what ive seen in other people and on zzps website it lowers about 2* on avg. I have one and have no way right on detecting knock but car did seem to breathe better and better acceleration.
 
'04+'s don't have a U-Bend...so that's a benefit.

Get a larger downpipe and the PLOG...I'm sure it'd take it away.

For the money you blow on a PLOG/DP...you can get headers for the cheaper on EBay and kill even more KR.
 
I know headers would be more beneficial and about the same price, but there a little more involved with installation and i feel like a little bit of overkill for what im looking for. I'm not looking into deep modding the car i'm more of just looking to prolong the life of the engine.
 


Then I wouldn't even waste my time with the PLOG and throw a 3" downpipe on it and be done. You don't move enough air to justify it anyways if you just want more longevity out of the car.
