The Best Plugs For The Job

Hi All,

 

Once my Supe is finished it will be running 1.4 bar through twin stage 3 hybrid turbos. What in your oppinions would be the best plugs to fit. I have already bought the Denso IK22's but I've been advised to use the normal NGK plugs instead. This is due to the fact that the NGK's simply melt under heat whereas the IK22's will deposit a large piece of debris from their tips that will pop in to the engine.

 

Any advice??

 

Cheer All, Andrew:thumbs: :search:

A lot of people swear by Denso Iridiums, but personally i won't use them, i know a few people with various turbo cars, who have popped an engine for the reasons you mentioned, due to there small electrodes they have a tendency to damage the porcelain insulator when the electrodes melt due to det, and it these that do the damage, i always go for NGK either platinums or copper.

Yeah we dont use Denso IK's anymore as they seem a little "fragile". The NGK IX's are holding up really well.
