SEMA 2013: U-Build-It Kit from Airaid Makes EFI Intakes Easy

Transplanting a late model EFI engine into a classic musclecar can be simple or brutally difficult, depending on whether you’re doing something that’s been done quite a bit, or breaking new ground with your engine/chassis pairing. One common factor in every swap, though, is the fact that you’re almost certainly going to have to fab up an intake system for yourself.

Airaid’s U-Build-It line of kits and components let you assemble a cold-air-style intake for your EFI engine in 3-, 3.5-, 4-, 5-, or even 6-inch diameter, limited only by your imagination. The basic kit comes with a selection of straight and angled tubes, couplers, reducers, hump hoses, and of course a high-flow washable air filter. You can also get components a la carte to custom-build exactly what you need.

This year at SEMA we got a look at some new additions to the line that are essential for any EFI intake – Airaid’s MAF adapters. Available in 3-, 3.5-, and 4-inch sizes, the adapters can be ordered up with Hitachi or Denso MAF mounts, which cover the majority of OEM EFI applications, or with a blank plate that can be machined for your custom application.

Speaking of custom, Airaid also offers Cold Air Dam components for 1967-69 F-body and 1968-72 A-body General Motors cars that keep the filter element isolated from engine bay heat while drawing in cool outside air. Used in conjunction with the UBI system, they’re a trick solution to keeping your swapped classic breathing easy.
