Be carefull with the plugs, its PFR7bs in some, but I know Hawkeyes use different plugs, maybe Legacy might be different aswell..????
Are your plugs Iridium?? Signified by (I) at start of part number????? Better check that Dan

mostly depends on the level of modification....pointless on standard cars but worth checking out dan!!

Code for the hawkeye are ILFR6B (have a set in my hand) so possibly ILFR7B for the 7's, that is if there long reach of course

Yea putting long reach plugs in if its short reach plugs thats needed might not end up good
