What Plugs for EJ25 STi Hawkeye

[Scott.T]

Was going to wander into my local motor factors for some PFR7B's but Opie oils lists something else for the EJ25 (not PFR6B's or 7B's).

What do people recommend ??

[ralliart didz]

spark plugs in your car silversurfer are ILFR6B (NGK)

[Scott.T]

yeh that's what I read, just wondering if the PRF6B or 7B are a better choice.

Go for 7's, the Hawk plugs are a longer reach plug than the earlier models.
But as above standard are ILFR6B

PFR's are short reach for 2.0 models and pre 2005 2.5 STi engines.............

the later 2.5STi uses a specific plug as DB states above, we normally stock these in ILFR7 as an upgrade........
