Re: professional products intake manifold for 5ltr
It's a very poor knock off of the Edelbrock RPM. Firstly because it is based on the RPM intake, it's power range is a little too high for most setups out there, you will loose quite a bit of low down torque and idle quality. Secondly the quality of the casting is suppose to be absolutely crap. I have not seen it for myself but the inside needs a lot of work just to get rid of all the casting leftovers and flaws. Also reports that many had no thread tapped into the lower intake. They may have sorted out their quality issues since their release about 12 months ago, but I wouldn't really trust them. Pay the extra $400 and get the edelbrock performer.
