Under hood hot air can heat soak the air going into your engine and rob your engine of horsepower. For this reason, Spectre has engineered these universal air intake systems for classic V6/V8 muscle car/pickup models with a GM factory or aftermarket throttle body injection assembly or carburetor with a 5-1/8 inch neck. This air intake system uses a chrome low profile, 14 by 3 inch tall round air filter housing with dual inlets positioned 120 degrees apart and a set of two black flexible air intake ducts. The zinc-plated drop base provides increased hood clearance and requires only a minimum of 2.4 inches above the carburetor/throttle body flange. To help block the hot under hood air the two tubes can be routed to a location that will provide cooler outside air.
  • Designed to increase horsepower and torque
  • Chrome air filter housing with black intake ducts
  • Low profile with drop base requires only 2.4 inches of clearance
  • Includes a 12.6 inch diameter by 3 inch tall air filter
  • Classic V6/V8 muscle car air intake system

The Spectre Cold Air Intake is very nice & easy to install. As for the Spectre Accessories they are nice, I think a little too pricey for chrome plastic. but then again they got the only underhood chrome knick-knack out there for the Camaro. And that's all I can afford with fighting pancreatic cancer. Just trying to make my car nice for my kids when I'm gone.

Installed on 74 F250 460 cu cam, headers, performance intake, summit 750 cfm. Spectre Shipped it the same day, can't ask for any better than that. The base pan had too much drop and hit the my carb (Summit 750). I had to add a spacer do some modifications to get clearance. It had a scratch across the top on the back side of the housing, but you can't see it when installed. Way quieter than the open element I had on it. Seems to run as strong or stronger as with the open element. Looks very good installed.

The BEST and most effective low cost part I've ever put on my 86 Bronco carb 5.0. Throtle snap rpm went from 2000 to 2600. Piped it out beside the headlights for fresh cold air. Doubles as ram air. Has been on 1yr now and paid for itself. 5 stars!
