Cheap eBay Intakes

I believe @Johnny Dart has done some testing on these cheap knockoffs vs the real deal Edelbrock RPM and concluded that the performance of the real RPM was well worth the price difference. I could be wrong, but I vaguely remember reading that somewhere. Maybe he'll chime in.
Can't say I've done any testing on the knock off, but I'm sure I've talked Chit about it. :p

From what I've read, they work pretty well for the money.
Do a little interweb search, I'm sure there will be a thousand hits on it.
