Poor Quality Main Jet for Automotive Performance

I purchased a standard main jet for my performance car's fuel system, and I was extremely disappointed. As my tests showed it was poorly made and caused my engine to run rough. The only positive aspect was that it was affordable. However, the cons outweighed this, including the negative impact on my car's performance and potential damage to the engine. Overall, I would not recommend this product to any automotive enthusiast..

Pros
  • Precision engineered to optimize air/fuel mixture for increased performance and efficiency.
Cons
  • May not fit all types of carburetors.

Exactly as described.

I received the main jets immediately in new Holley packaging. The injectors are easy to assemble with a large flathead screwdriver.

Pros
  • Fits all Holley 2010, 2300, 4010, 4011, 4150, 4160 and 4500 models
Cons
  • No
