These oversize CNC-machined castings replace the factory designs used on Delphi®-equipped 2001 and later models, and are designed to accept the factory electronic components so assembly is a snap. Our ThunderMax High Flow Air Cleaner includes a beautifully CNC-machined billet backplate, 2-3/4” deep high flow filter, breather plumbing and heavy-duty support brackets. Fits all years of ThunderMax throttle bodies.

2001-2005 Models – Throttle body and manifold are sold separately but must be used together. Throttle bodies available in 50 and 54mm; high flow design requires ThunderMax air filter with spread bolt pattern. Manifolds are available for most popular engine kits from 95” up to 124”, with standard (1.625” ID) and oversize (1.780” ID) intake port options.
