Fancy BOSCH spark plugs

Hi!

Recently I saw some fancy BOSCH spark plugs in a KRAGEN auto parts store. They have four electrodes instead of usual one, and claim to have longer and generally better spark. They are more expensive than regular ones but still cost some insugnificant amount of money, like $3 or so. I was wondering whether it is a good idea to replace the plugs in my car (Honda Accord '92) with these, or better not to try to fix things that are not broken?

Thanks!

Regular Bosch Platinum plugs are excellent. They usually cost no more than $2 Bucks a plug. 4 Electrodes don't make the path of least resistance a better spark plug.

$2 for Bosch platinum. That sounds pretty cheap to me. Some of those plugs are over $10 to the dealer.

If you arent going to put the original NGK plugs in your Honda at least use Nippon Denso plugs. They are Japan made and the same as NGK. Bosch plugs dont fair well in some cars. We stock Bosch plugs and my manager insists on using whats on the shelf, but I insist on the correct plugs, whenever I can convince him. Its my rep on the line when the customer comes back in a week with misfiring. If your car doesnt call for platinum plugs you arent going to gain anything by using them.
Hope this is helpful to ya,
Billy

I agree with billy the best plug is the one it came with.This holds true for any car.Engineers don't just slap stuff together.Well most of the time they don't.

Actually the Bosch Platinums have proved to be excellent in every application I have used them. They've got me sold. I used to always follow the religion of champion=Chrysler, ACDelco=Gm, AutoLite=Ford, etc. And I still do believe that, but these Plugs have proven to me they are excellent along with their ignition wire sets.

Not all applications are in that price range. Some of the double platinums are considerably more.

I agree with Billy and Davo. In some applications, Bosch platinums just run like crap. Their main claim to fame is their longevity. Most of the time there is a performance loss in exchange for that benefit. I only use Delco platinums in OE GM applications, and stay with the OE in all the rest.

Yep... More like $15-$20 each. My mother-in-laws 2002 Camry has NGK Iridium plugs. When I did her 30K service I checked them and they still looked brand new. Supposed to be good for at least 80K.

I didn't say the double platinuims were in that price range. I also stated 4 Electrodes don't make the path of least resistance a better spark plug. The regular platinums are good plugs and are affordable.

Who said they were?

Regular Bosch platinums rum like crap in most domestic applications. I'd pay extra NOT to use them.

I have Bosch Platinum in a 1990 Accord, 94 Camry and 97 Kia Sephia. All run perfect, and the plugs still look brand new after 30K miles.
But some cars (imports especially, but some domestic also) don't like Platinum plugs (not just Bosch). Also, platinum plugs with el cheapo wires are not a good combination.

I've tried the Bosch in '89 5.7 GM and on '87 MK1, MR2. I'll never buy another set of the Bosch. Staying with Delco and NGK.

My 2 cents. I have used Bosch platnums on all makes and modles for about three years and never had a problem. Through the years I had problems with ac delco on gm autolites on fords and especaly champions opn chrysler. NGK always worked out for the japs but I still use the bosch platnums due there low cost and awsome reliability

if you had a problem with champions in a chrysler, then you had the wrong champions

i've removed plenty of high dollar plugs and installed 99cent champions to smooth a choppy idle out.

no, $1.99 is cheap, but when i have to take them out, it's NOT cheap anymore.


why have one electrode be platinum and the other steel, you're defeating the purpose of a platinum plug, a true double platinum plug, which is what supposedly lasts forever?

As compared to a copper electroid the one platnum center electroid (the one that mostly wears) last longer

OK, the only reason for the use of double platinum is in DIS situations. The reverse polarity of the return spark causes the wear to the outer electrode instead of the center tip. Double platinum elimates that. sdsdogg2, you seem to be the only guy in the business that likes those things. I also have repaired numerous misfiring engines by removing those pieces of junk and replacing them with Autolight, AC, Champion, NGK etc. Bosch platinums are junk and you can't convince me or most of the other techs here any different.

So the pissing match is over now?
I don't get some of the arguments on here, just mysterious wastes of time

This thread has run it's course.We can't argue here folks.It's a spark plug use what works for you.The original poster should be able to decide which plugs to use at this point.Thanks to all for their advice.
