I actually stacked a street Dominator against the action plus and factory cast TQ intake on a 318 with a summit cam. The slowest ET/MPH was the SD. Action plus came in second, and the factory cast TQ intake actually made the best ET and MPH. HOwever, all were within about a tenth and a half. I think sometimes a little too much gets made out of street intakes.
100 bucks. I have one I picked up for 100 4 years ago. As far as wall art or door stop a bad combination ,gearing,tire diameter ,converter, and weight will make that intake bad. But with the right combination it can work.
