snowtoy's right. i see alot of people try to save money by buying cheaper parts through the major parts chains, but end up spending more by bringin it to us when it doesn't turn out working right. it makes people kinda angry when they bring their freshly tuned up car in complaining of slight issues, then i turn around an recomend the same parts that they just replaced. i dont like doin it, but it usually fixes it. i would never recomend using any type of sensor other than stock, same with electrical items, because chain stores usually develop a part, and then duplicate them for different makes and models. i'm kinda kickin myself in the butt right now, because my autozone alternator is starting to give me issues, and its only been on there for 20k. i wish now i woulda bit the bullet and bought an oem for another $40, but oh well, to late now.
