Hi there im going to change the plugs this week before my car gets a remap.can anyone give me a bit of advice its an sti8.Do you get them from above or underneith the car.The new plugs are NGK 429pfr7b, are these pre-gaped or do i need to gap them, if so what should the gap be,Also are ther any good tips as how to get more cold air up to the standerd air box as i dont want an induction kit thanks, Sean

 

Come on guys, can no one give me some pointers

 

Gap the plugs to .06 to .07

 

Thanks mate,anyone else got any info

 

You get the plugs out from the top mate,they will need to be gapped up, its a bit messy to do, battery out, air intake out etc,but should take you less than an hour.
