Spark plugs - longer lasting than copper core 5 Months, 2 Weeks ago Karma: 26
Hi guys,

What spark plugs are you using?

I'm using NGK BKR7EIX, for the past few years. These are usually lasting for 30.000kms. After 30k, my car starts hikkuping under full boost. This is the case again now, so I need a new set.
Dizzy, rotor and leads are relatively new (~10k).
I could re-gap it, but I prefer not to after so many heat cycles. I gap them new to 0.8mm. I'm running stock boost, around 1.1 - 1.2bars (Rev3)

I'm thinking of Denso IK22TT's. These are the same heat grade, with double tips, also considering the platinum version which is PK22TT.

I know copper is the best performer, but I don't want to change it at every oil change. I put 600kms in my car every week.

What longer lasting plugs would you vote for?

Thank you for your input

Cheers
