Do you know the story of your Fuel Injector? Can you say it will last a billion cycles?
We can, but our competitors can't.

When it comes to fuel injectors, we all know there are two main reasons for failure: excessive wear and deposits. And, when you shop the competition, there's no guarantee you won't have these problems weeks after your installation. Why? Because while our competition knows how to make a fuel injector shine like nobody's business, they're not the experts in getting that sweet-source-of-power to last another million miles. We are.

Each and every fuel injector from Highway and Heavy Parts has been fully disassembled, thoroughly inspected, and cleaned to perfection. Once that's complete, our suppliers (who also supply the OEM's) replace 100% of the critical components.

The result? The best ride of your life brought to you by a perfect seal, and a little extra jangle in your pocket with increased efficiency.

Need a little extra proof? Let's talk shop.

  • Quality should always be a given when shopping for parts. you will receive a brand new MUI fuel injector that is manufactured and assembled in an ISO 9001:2015 certified facility. This ensures quality and consistency.
  • Finding the right parts can be hard but we can make it easier. All HHP parts are crafted to strict OEM specifications which gives you proper fit and function.
  • Our fuel injectors go through rigorous testing to ensure great quality. Each injector is 100% functionally tested for fuel delivery, fuel injection pressure and timing to ensure you receive the highest quality.
  • Give your engine that extra boost. A new fuel injector will increase power and decrease emissions. 
  • Why pay an arm and a leg for a fuel injector? Our fuel injectors have equal or better quality compared to the OE at a much lower price.
