Best spark plugs for `01 OBW.

B

Bradley Walker

Hey all,

I asked the dealership the other day what the best spark plug was to use for
my 90k servicing. I told them I had saw the Bosch Platinum 4+ which had 4
grounding terminals to create better spark. I was told that was a bad
decision because it puts too much strain on the alternator and electrical
system causing burnouts on electrical components due to stressing them out.
He recommended the NGK brand.

Thoughts, suggestions?

well, the reason given is BS (IMHO) - but NGK iridium is probablt the
'best'. many folks just go with NGK copper and change them per schedule.

I dunno

Use the stock plugs. They've worked fine up to now, haven't they?
 
I was wondering though, if others like the Bosch Platinum +4 would give any
minor performance boost though? Especially in hilly mountainous terrain
around here or in the cold winters?
 
Some folks have has minor issues with the +4 Bosch plugs in Subarus. I
use the standard NGK copper or NGK-V coppers to great success.

Has you car performed poorly in either the hills or winters? If not,
why change? If yes, it may not be spark plugs you need.
 
I just purchased it last January, and the winter was mild enough that I
really didn't get a chance to test it. I figure while I am doing 90k
service, I'll get good plugs to put in there... that is so I thought the
Bosch 4+ ones were good.

Hi,

Personal experience: nothing Bosch makes or markets comes close to NGK.

More personal experience: nothing anyone else makes or markets comes
close to NGK.

Am I sounding repetitive yet?

I've seen numerous posts over on NASIOC, for WRXs
and STI's, where guys suddenly encountered odd
idling, misfires, etc immediately after
installing Bosches. Returning to NGKs eliminated
the misbehaviors just as quickly. Never seen any
explanation, just those reports
