Can anybody clarify this to me ?

Is the KL sensor different from the stock knock sensor ?

 

Yes.. different.

It is a Bosch part and I think the standard one might be a bosch too but they are definitly different.

Also you cannot connect the knock link into the standard sensor as it will take some of the sensitivity away from the ECU.. not that you mentioned doing but just thought I'd say.

Knock Link sensors I think TweenieRob might have a source..
Or BR Developments sell them... if you can get the part number you can of course go direct to Bosch probably..

Thanks for the input.

My point is just not to buy the KL sensor if it's not mandatory.
Seems it is... maybe BR can confirm ?

Cheers

 

is this maybe a cheaper option ?

if you mail the guy that you can buy it elsewhere for $139, that's then the price you'll have to pay
