EFI Is All We Do!

Howell Engine Developments, Inc. was formed in 1988 by Bill and Matt Howell to support the growing trend towards the use of electronic fuel injection in the Hot Rod/Street Rod and Four Wheel Drive Industries. At Howell EFI, we do not make a one size fits all product line. Our customer support team knows every question to ask to make certain that what we ship covers every possible base for a complete and easy to install system. All kits are covered by a money-back guarantee.
