Denso Difference?

[Mz3Hatch]

So I went to buy Denso spark plugs today online and I was going to get the ITV22's that seems to be what everyone recommends. But when I searched for our cars, the inquiry came back as the ITV20's should be used. (uhm)Difference? Cant seem to find anything about the difference in the 2. I know everyone is saying the 22's are shorter than stock but what about the 20's? Thanks for any info or help!

I would like to know as well. I think that they maybe a step down or "colder" as they say. I dont know if you can go too cold though lol.

AFAIK the ITV20 is the same heat range as stock. The ITV22 is one step colder and the ITV24 - 2 steps colder. If im wrong someone please correct me.

You are correct.

I'm sure that the engine will run fine with a fresh set of ITV22's but I wonder if they are going to be prone to fouling...

Thats what I was thinking at first but wanted to make sure and confirm with the forum. Ordering ITV22's now!
