Spark Plugs

[thewelsho]

My 30k service is WELL overdue so I need to start getting some bits together. I already have the one step cooler plugs in my MY06 WRX but I can't remember for the life of me what the part number is!

Anyone know?

Please remember that the plugs for the 2.5 are different (longer) than those used in the earlier 2.0 cars

I think the part number you quoted Wilky is the plugs for the 2.0 engine. The 2.5 plugs are longer.

actually the blocks are the same wether its a 2L or 2.5L but its the heads that are different.

The 2.5L heads needs the longer plugs.

That's interesting.

Whats the difference between iridium plugs and platinum plugs well different metals and what else

apart from the different metals the iridium plugs have a much smaller tip on them iirc, which is meant to give off a better spark and last alot longer than standard.

It was recommended to put the longer cooler EVO Plugs NGK ILFR7H in the 270 for the 2.5L engine when I had the mod's done they're about £12 a pop

cheers Bobby, I'm sure that's the ones I have

I thought I might be mistaken, but in the NGK ranges, a 7 is a cooler plug than a 6. Here is a link to the NGK instructional page.

Useful NGK information

I also heard they were prone to breaking off with the smaller tip etc....
