Be wary of super cheap sensors. They might as well be a plug. My dad bought a sub $10 knock sensor for his S2000, threw a check engine light immediately. The proper working sensor was in the $90-130 range if I remember correctly. Buy once, cry once.
Also, check out this thread on modding a Honda Pilot for some ideas.
