are bosch platinum +4's decent for the price?

 

you really don't need them, just stick with regular platinum plugs, either bosch or ngk.

 

stick with ngk or denso

 

no, just get NGK.

 

my car ran poorly with bosch plats.
changed them out the same day for some ngk's

 

i liked the bosch 4's but i just switced to ngk today. i think both are fine. justa little more money for the 4's.

 

I didnt like the way my integra ran with +4's. Though they were great in my mustang. I have NGK Irridiums Love them

 

stick wid iridium type .......bosh P+4 is just 4 ground so your plug last longer.......its your decision

 

i just bought bosch platinum +2 but i have not installed them yet
so am i experiencing a downgrade from stock? it sounds like you guys are saying that these are BAD, if you are swtiching them out for NKG

 

i dont like the bosch plats period. i put the 4s in my friends prelude and it seemed to run better w/the ngks that were in there before. also, i dont trust them bc when i looked in my parts system at my store, i noticed something i didnt like. for example, plug #4441 (im just making up a #) would say its for vehicle A and that the gap should be preset at .044. then, id find that the same plug # would be used for a totally different vehicle, B, and that it says the gap is preset at .035. well, the plugs are pregapped (all the plat 1s, 2s and 4s) and you're not supposed to gap them and its impossible to gap the multi tip ones anyways. so yeah, how can it be 2 different gaps yet say its the same heat range and everything else as all the other brand plugs for the application? i also had many customers complain, saying thier vehicle didnt run right. dont get me wrong, sometimes they're fine in the right application though but i just dont trust them in every application. so yeah, i always use ngks.

 

Previous owner had +4s in mine, I had the car for 30k miles before they started to foul under load. Figured, what the heck, and replaced with same. it's been since about 180,000 miles (fouled right after clutch and timing belt change). It's been at least 50,000 miles.
