I was thinking of Buying a set of NGK iridium spark plugs for my 93' bonneville SE non SC. Are These GOOD FOR OUR BONNEVILLES! Ive read
in previous topics of people using BOSCH triple PLatimums and getting poor results. Will i get the same poor results with the NGK PLUGS? Has anyone had any experience with these Plugs? if so what are the performance gains? THANKS.......

I'm running the NGK Iradiums and loving them. I had done a few different things at the same time I put them in (plugs, wires, filters, etc...) and I did notice a difference. I think it is worth the money for them.

I think that the prefered plug by most Bonneville owners wil either be the NGK or a good set of ACdelco'*.

my $0.02...

just out of curiousity, how much to NGK iridium'* cost?
and whats the part number?

Here is the info...
GrandPrixStore

a set ofTR55IX Iridium'* is the thing to go with then 'eh?
i made the mistake of getting double platinum plugs before i knew about NGK'*
next paycheck i know what im gonna be getting.

Just to remind people here.....NGK makes ALL the Spark Plugs for GM (AC Delco) BTW! Therefore the AC Delco Platinums ARE NGK'*!

Hmm... just adding - Bosch Platinum +4'* are ***... all sorts of vibrations and such... I'd stick to AC Delco Rapidfire'*... :P

I just installed my NGK'* along with new Taylor Spiro Pro'*....

Most defintely a noticiable difference...I recommend them all the way....

Thanks for the response! I just ordered a set of ngk plugs a couple of days ago. I plan on gettin an MSD DIS 4 later for Xtra performance. I have to try to slip it by my better half first

Just a quick comment on plugs. Make sure, if you are running an MSD system, to stay away from any platinum plug.
