can i use Platinum Plugs for my 1991 3.1 liter RS ?
please help

 

yeah, just so long as you get the right #

 

Go to almost any part store tell them them you want bosh plat and tell them you have a 91 camaro 3.1 and they will look up the numbers and pull those puppies off the shelf for ya !

:lala: <--- looks like he has the flying $hi*s the way he comes running around like that

 

thanx for your help guys
them bosch plats. are like 4 bucks a piece at PEPBOYS
no wonder their so happy so sell them to me LOL

 

Not worth it.... My ignition is as modded as they come and stock work the best

 

I wanted to say that , but didn't feel like being flamed ..lol ....Well let me tell ya what i did . I drive on the interstate alot .passing people lugging it sometimes .I have cracked two ac delcos aleady so I got some bosh . I have not installed my bosh yet .But the bosh would deffinately hold up better under those lugging and interstate driving conditions b/c its a lil bit better quality plug , you can feel its better quality .But if you just drive around town and don't get on the interstate regularly like i do every week two or three days a week , Id just stay with your ac delcos . NOW , you might notice a very slight difference mainly top end if you have an ignition box some platnum plugs , the whole modded deal you know .But with just my new 8 mm wires on there do I see a difference ? no .BUT , they hold up better under all that heat and they are insulated better .:rockon: But on the whole , I think stock is just as good .Mainly to notice a differece in power you have to have atleast a few mods .

 

I would've pushed Splitfires (and still will for a stock ignition), I've used 'em for years with no problems with just an aftermarket coil & wires- but check out my newest post about "EGR and prep for smog test".

 

From what I hear the SplitFires foul out really easy

 

Splitfires do.. I had 4 go bad in tow years when I bought into that gimmick.... Stock AC Delco have always worked the best for me..

I have an Accel Box, MSD Coil, Crane 8.8MM Fire Wires and I would not ever put any platiunum plugs in the car. 99 cents and every year I put new ones in for FUN!!!

 

Just like I stated above ,platnum plugs are better quality if you do alot of interstate driving , and lugging it sometimes .I cracked two ac delcos that were two months old . I went and purchased some platnums .You can feel the better quality in them when you pic the platnum up .It's heavier , you can feel the better quality .AC delcos are good , just not quit as good of quality .They dont hold up as good in those , interstate conditions of high speed , heat , and an hour of driving on the interstate .And also for the price of platnums , you can keep them in there longer .Ya get what ya pay for !

 

I personally have had the best luck with the AC Delco Rapidfire plugs. I use them in all my vehicles and every one has responded positively (even my wife's Geo Metro). Plus there made by AC to satisfy the "use stock parts" philosophy and has a platinum tip (new design -- the old design had a star shaped electrode) for the Platinum/aftermarket crew.

 

IMO, Autolites are the best plugs out there.

 

Odd; I never had a set of Splitfires foul on me; and I've been running them (except for one year with Accel U-grooves) since 1994. They might've had the wrong heat range for your year of engine. By going thru the Splitfire application charts, they didn't follow GM's exact heat range change. I have the file somewhere; don't want to look it up, but GM changed the heat range twice for our engine's spark plugs. They changed it once in '85, and back again around '88.

 

I never tried splitfires in a vehicle
but in my dirt bike they lasted about 10 hours and the bike was brand new.
I guess thats why I never tried them again.

 

My car travles 170 miles a day and when I was using the stock replacment plugs I had to change them every month. After switching over to the splitfires in March of last year I have only gone through one set. I went through the one set becuase I used to have a habit of lugging the engine this caused the electrode get blown off. Other then that I clean them once every 3 months. ! month of driving for me = 680 miles plus 100 or so for weekend driving. I would say that they hold up pretty dam good.
