I was using the k8 plugs, worked well for me until I flooded the engine with water.

k8 standard densos or ngk

The issue with KLDE plugs in a KLZE is that they would get hit by the pistons. a KFZE might experience the same problem.

it was my understanding that all kl engines are non intereference engines. I know the klde, and kl08 are non intereference.

Non-interference as in the valves won't hit the pistons if the timing belt snaps, but won't take into account spark plugs that are longer than normal...

[Newfie_dan]

so long as he matches the plug to the proper engine he should be fine, I have heard good things about the diamond fire plugs but have not used them myself as of yet. The stock plug has a projection of 1.5 mm as for heat range I am not to sure what best suits the kfze. The diamond fire plug number is; E3.48 if your interested.

I used NGK Iridiums. Get them for the Probe FS 2.0L 4cyl
