Guys,

I have a RB5 with a Ninja exhaust and soon to be a Centre De-cat.

When I bought the car it came with a dyno-run which had been done previously which showed the car having 245 BHP. Now as far I know it hasn't got PPP but I could be wrong, as I don't know how the car has 245 BHP.

I'm looking to change the plugs and leads soon but to which ones I'm unsure.

The NGK PFR6B are for the standard UK model and the NGK PFR7B for the modified model's.

The 7B plugs, are they for heavily modified cars with extreme amounts of power or for something like I have.

Any help would be appreciated.

Cheers
Matt

 

Give the 7b's a go.

 

Mine's running around the 310BHP mark (approx) at the moment and I still use the PFR6-B's. I think the 7's will maybe run okay (they're meant to run colder) but there's no need for them with that power. No need really until you start pushing the 350-400BHP mark. Save your money and stick with the 6's

6's are normally little different in cost to 7's, you just need to know who to buy from!!..................and to be honest unless the car is totally std 7's will offer more protection/performance.....................

would be my personal choice, alyn
