Review on Holley 122 68 Standard Main Jet by Aaron Boudreau

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..
