what do you guys prefer for spark plugs between ngk's and bosch platinum 4.

 

ngk, i personally dont like any bosch plugs especially those gimmik expensive platinum ones. Just get a set of ngk v-power and you couldnt be happier.

 

Bosch plugs suck, and the +4s run way too hot. Pick up some BKR6E-11 NGK Plugs. Get BKR7E-11 for High compression.

 

its funny you should post this, i just replaced my ngk iridiums for bosch platnium +4

i noticed no difference whatsoever. at first i thought the bosch felt better but the iridiums were a year old by then, once these settled in they really feel about the same.

o btw, b16a i/h/e

 

yeah my motor did run hot with those platinum 4's so i just switch to ngk's

 

Replaced my Bosch Supers (for 96-97 Del Sol VTEC) with the standard BKRE6-11 NGK V powers on my B16 and noticed a difference immediately. Better idle, more power and much better fuel economy. I'm getting about 50 more miles per tank now.

 

I love my NGKs Been running nothing but NGKs for 4+ years now with no complaints.

 

NGK all the way. With Iridiums, I never noticed a difference really.

 

Ngk plugs all the way, I have never had good luck with bosch plugs

 

You'll be fine with NGK's.
