i thought all bosch platinums were +4s design. you still probably paid close to $10 each for them the ngk platinums are like $12 i think. i still i would not use platinums anyways, they are not a performance plug. they are a plug for lazy people who want to change plugs every 100k. if you want extended plug life i would get iridiums which ngk makes sells for like $7 each and will last about 50k or so.
