Spark plugs for hawk WRX
 

Anyone know the correct plugs for a 2.5 hawk WRX with a remap ie more boost. Thanks

Ngk iridiums off ebay £ 30

how much more boost?

ILFR6B for standard or slightly tweaked cars.
ILFR7H for more modified cars.

Not exactly sure mate but it was a JGM remap. Could probably do with changing the spark plugs soon as the car is 3 1/2 years old and still on the original factory ones

I had thought if running more boost you would need a cooler plug so in this case a 7H??

as butty said. ie- turbo upgrade- definate 7's.

I am running standard plugs on my JGM remap and it is fine, 3 1/2 years old they probably need replacing, even though Subaru say its something stupid like every 40,000 mile.

Was not a turbo upgrade just a remap.

So is it 6's or 7's or does it not really matter

Anyone know 6's or 7's??

7 heat range.

Go for the 7's

+3 on heat range 7 as requested by Andy F pre-map

Thanks guys 7's it is

... for the 2.5 engine - these are the long nose plugs. :thumb:

Do you have to state that when buying them??. Think they are the same plugs as the Mitsubishi Evo

no - the code says it all
