I have to pick up a MAF tonight from ECS and I wanted to get a decent set of plugs.What is my best option my cars stock I was going to get the Denso Iridium Plug then I saw some posts that they where bad for turbo engines.So what plugs are best for my car and the longevity of the plugs.

your supposed to use irudium plugs with turbo engines. Deff. dont use platnuim the tips tend to break of and will destroy your turbo.

 

Ok do you know if the Denso Ik20's are OK to run they have A very small tip. Someone had said they don't heat up enought for the turbo engine. They said to use the Ik22's plugs what do you think?

 

Ok I ordered the Denso Iridium plugs Ik20's

 

i had those in my 1.8t and they worked fine unless i was under full boost (18 psi) my car would spuder so i remove them and installed the ngk cheapies and no more spuddering i don't rember the ngk # it was b7??? but my car came stock with the ngk irrduims and they did the same as the denso's
