Spectre's polished cast aluminum low profile plenum has a 4 inch inlet. It is 2.4 inches tall between the carburetor and the bottom of the hood which makes it great for low clearance applications. It measures 9.25 inches from the air cleaner stud to the inlet and 7.25 inches across the plenum at the air cleaner stud. This plenum fits carburetors and TBI throttle bodies with a 5-1/8 inch inlet. The 4 inch single inlet is designed to match up to all Spectre 4 inch tubing, filters and accessories. Use with Spectre 4208 air cleaner nut (sold seperately).
  • Polished aluminum finish
  • Low profile design for increased hood clearance
  • Designed for 4 inch diameter intake systems
  • Single 4 inch inlet

January 28, 2017 - Part 98499
Installed with Spectre in-line box PN 9831 and fittings/pipes to draw in air from scoop under front air dam in 1984 XJ12 with GM ZZ3 conversion. All Spectre parts very good quality and appearance. Much better performance than (Brand Replacement) pancake filter. Also bought large Spectre filter for Navy RHIB with Cummins turbo diesel..... perfect fit.

Worked great under the hood of my 80 Corvette, with 383 stroker motor. Has a high rise air gap intake, so room between the throttle body injection, that I put on it also, was close. Fit great.
