ThunderMax EFI Intake Systems

Building A Performance Big-Inch EFI Engine? Zipper’s ThunderMax EFI Throttle Body, Manifold and High Flow Air Cleaner assemblies provide the big airflow required for larger performance engines. 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 CNCmachined 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 Delphi® 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.  Includes intake seas; uses original equipment intake flanges (not included).
