Which is better Surplus Distributor or
Bnew Replacement(what brand)?

Need kasi palitan CKP sensor tama ba nasa loob yun ng distributor?
Pwede ckp lng ba o need buo distributor?

Yun nasa gilid ng block pulley area CKF sensor lang yun for misfire detect only marami nag bypass nlng ckf.
Ang Main crankshaft sensor CKP nasa loob distributor?
