If it's not really about tuning or wiring. Then it belongs in here.
i am searching for a bosch style wideband knock sensor to wire into a haltech elite, came across SRS:
has anyone used them or these sensors? prices are very cheap, maybe too cheap...
any other reputable sensor sellers?
I usually just order them from my local motor store, Bosch part no 0261231006 They don't cost much at all
just stick to original Bosch - the price difference is not that much, especially when you consider what you are using your knock sensor for.
