Most Chinese knock-off parts are crude, heavy, or porous, or so light they move around with heat, and ugly replications of the good stuff. I have had three Funnel Web 302W intakes in my hands just recently to try to find the best one. A real one from Australia with the logo on the bottom of the intake, and two different knock-offs. One was so crude that I refused to do anything with it. The real Funnel Web flows over 370 cfm, and is a really neat manifold, but has thin bolt bosses. Otherwise it is an exceptional intake for a high performance 302. One of the knock off intakes is a very good copy, and it flows in the 330 cfm range. I have had that intake for 13 years, and it cost me $150.00. I thought it was real until I actually got a real one in my hands to compare. The biggest difference was the logo on the bottom, and the placement of the logos on the runners. Other than that, it looks nearly identical. The last one was a piece of junk that is a recent version, and it has EFI bungs all in the wrong places. Junk! I have done several SBC, and SBF intakes for folks that were cheap Summit/Pro Comp knock-off parts, and they are difficult to keep the burrs clean because the cast aluminum is just junk aluminum. So, using Pro Comp, Speedmaster, or whatever Chinese knock-off parts is a risk at best IMO. BTDT on too many intakes over the last 20 years. Give me a good Edelbrock, Blue Thunder, or Buddy Bar any day. Joe-JDC
