Don't go platnum. If you're sticking N/A, get hotter plugs...

I've been running Bosch Platinums and Plus 4s since they came out. Great longevity, good milage, and no noticable problems. What am I missing???? Jim

I've been running bosch+4's, with stock wires. When i dropped them in, i felt a difference in the response of my engine.....TIME FOR WIRES! GO FOR THE BOSCH+4's RON!!!!

Well i just remembered that they didnt make them for a 2002 protege5, but they do make them for a 2001 protege (2.0L) and they work well! No problems what so ever! They are platinum quad tip.

normally aspirated or naturally aspirated depending on who you talk to... the opposite of forced induction... n/a simply means you DO NOT have a turbo or supercharger and are not forcing induction (forcing air into your engine)

As far as I know, platinum plugs run COLDER, which you don't want in an N/A setup. For an N/A setup, you want hotter plugs (I think)

what the plug is made of has nothing to do with heat ranges......whether it's platinum iridium or copper.....platinum and iridium just last longer than copper...which means they create better sparks over the long run.....they also reach their self cleaning temp faster which reduces the liklihood of fouling.......the heat range on the plug has to do with how much of the insulator is actually touching the the center electrode.....cold plugs have more of the insulator touching the electrode and in turn remover more heat from the engine....vice versa for hot plugs......unless your engine has a high compression ratio or is forced induction you'll want a hotter plug to let more heat build up in the combustion chamber to prevent fouling..........colder plugs help high compression or forced induction engines cool the combustion chamber to prevent detonation.........hope this helps in your choice

As far as I know (from the Bosch catalog), Bosch Platniums come in different heat ranges also. I walk up to the counter guy at the auto parts store and tell him/her I want +4s for a stock '97 Civic EX. They look up the plug and give me the proper heat range for that engine. If I pull a plug and it's carbon fouled or burnt, then I know I've got the wrong heat range installed. I've never pulled a Bosch platinum and found it to be either. Of course I've not pulled the plugs on the Honda as they were Bosch platinums from the factory. wink, wink, nudge, nudge. Jim
