I searched and couldn't find an answer for this. Probably a stupid question, but will a Cobra intake match up well with stock heads? What size is the TB opening, 70mm? Also, for anyone running a Cobra intake with a stock motor, what other mods did they need to make for it to run well? Bigger fuel injectors? Bigger MAF? I was offered a good deal on a lightly used original Cobra intake($250) and haven't decided if I'm going to take it or not. I was planning on acquiring in the future, but if this is a good deal and I wont have to put a lot of money into other areas at this time to make it work well, ill go for it. Thanks.
