Iv been doing a lot of research and still have not found a very definite answer.
What spark plugs will make the KLZE Engine perform the best?
Price is no problem, I just want the best for me engine.

Does anyone know if the KLDE Engine wire harness will work for the KLZE Engine?

Any recommendations or any for sale would be greatly appreciated.

NGK Vpower BKR6E-11

The main engine harness would work yea, it just may look or fit weird in the mx3 bay because its would be from a probe/mx6 or 626.. Better of sticking with the k8 MX3 harness.

As for the plugs, you can use the ones mentioned above or get the V-power BKR5E-11 as they are more common then the 6's which is a colder plug. The plug will be from a 1993 or 1994 Probe SE 4cyl. The stock KLDE V6 plug is a ZFR plug and is abit longer, it will work but they come awfully close to the pistons. Better off sticking with the BKR series. Also, don't bother getting Gpower or any other type of platinum or Bosch plug as they wont do nothing or will make the car run like a--.. ie. the Bosch +2's or +4's are complete crap.

I only ask about the harness because I had the DE engine first, now I'm upgrading again.

Thanks for the spark plug imfo

Yea the wiring setup is exactly the same from the DE to the ZE.

Now for his next question, what do I gap my plugs at. Not what Corksport recommends that's for sure.

.042 range is what I gap mine at usually IIRC
