M35 Plugs

[whitestag]

ok so ive done a little digging and found these two part numbers,

Denso Iridium IHK22

NKG LFR6AIX-11

but i also found HKS plugs (M35IL)

and NKG recomend LFR6AP-09

so i have two questions, which plug is best for the M35 ( highflowed if it matters)

and best place to get them, as 180 for plugs sounds steep.

I've got the Denso Iridiums, picked them up on ebay from the US, relatively cheap. No complaints, seem to be a few people using them.

The NGK suggestion is the same as what I use, other than the gap. As our coils are strong the 1.1mm gap is fine on the LFR6AIX-11's.

I buy mine from the US, and I buy at least 2 sets at a time to make the shipping cheaper. Perhaps you can go halves with someone local?

I found the IKH22's fail too quickly, the iridium tip had completely melted away within 20,000ks, the NGK's seem to handle the heat much better.

i got those NGKs from Amazon. Damn cheap.

Denso IKH22's.

Never had an issue with them and changed them after 100,000kms of my ownership.

I am using NGK LFR7AIX plugs, they are lasting well but I would like to take some more heat out of the combustion chamber.

I tried to find LFR8's but they don't make them, you jump up to expensive racing plugs from there. ($300 a set) Looks like I am stuck with the 7's for now.
