IMPORTANT NOTICE

Although Holley has greatly simplified EFI, the purchase of an EFI system represents the single most complex upgrade you will ever buy for your vehicle.

Where You Buy Is Important!

Over 85% of first-time EFI installers need technical assistance. That is to be expected. Even after you install a system or two there will be new challenges.

Why In The World Would You Buy From Someone Who Can't Or Won't Give You Outstanding Technical Support?

Here at HolleyInjection.Com we pride ourselves on fanatical customer support. Fast, friendly, accurate. We are not some huge speed parts warehouse that just pushes boxes with no idea what’s inside. We know not only the products and how to install them, but we understand Holley's long-term vision and know the products they are currently designing. When you use our online chat, call, or email, you will get a prompt response form a Holley Tier III technician. All for the exact same price you will pay when you buy from that big dealer that can’t spell Holley Tech Support.

Remember: Free ground shipping anywhere in the USA and 100% price match guarantee too!
