I swapped out the old knock sensors with these, and wow, what a difference! My truck runs way smoother now, and I don’t feel that weird lag when I step on the gas. It’s like it gave my engine a second wind. If your ride’s been feeling off, this kit is totally worth it.

That check engine light had been driving me nuts for weeks, and I was dreading an expensive fix. Popped these in, and the light went off immediately! My truck’s back to running like it should, no more weird engine hiccups. Couldn’t be happier with how this worked out!
