I've read up a lot on SRT-4's and I know that when you get an aftermarket BOV you must first get a plate to block off where the previous BOV was.

My question is:

Is this the same process with installing an aftermarket BOV on an EVO?

 

No this is not the case.

 

no most evo bov just drop right in. i have the go fast bits stealth fx bov and it took me 5-7 mins to install. very easy.
