Thread: Which Spark Plugs?

Tweet

I need to put some spark plugs in my newly aquired S-10 with a 305 V8, the plans for the car is stock setup with a 600cfm holly or edelbrock, which plugs do u recomend I use I was thinking of just using the AC Delco R45TS..

is that good or should I use something different?

also what gap should I set them at?

Dave

I use Accel high performance shorty headers plugs gaped at ..035 on my 305.

Accel eh? I heard they were not good for a normal every day driver.

Dave

any thing but ac cross over the r45ts to autolites

im sorry I dont understand what u are saying lol are u saying use anything but AC Delco, and I shoudl cross the part number form the AC's to the compatable autolites?

and use autolites instead?

Dave

yes i will not use ac plugs. but i am sure many do . i work at a boat yard and had many new boats that had alot of problem from lowspeed missing to hi speed missing and some that word not run at all .so after that i will not use them.so yes cross them over to autolites or bosch denso ngk

if you have a stock set up and don't know what you need, put back what ever GM put in it from the factory. i've never run nothing but AC or champion, worked ok for me. plugs are like, gas and oil, ask 10 people and get 10 answers. i think any of the top brands will work for st. use .035 should work. JMO

what are you smoking pat?

well like i said i work on over 5 boats a day and some had two engines in them so you can do the math and all the plugs that i look at were rim fireing and making many WEIRD things happing like two v6 chey that were jacobs ladder the dist caps the spark was walking the towers of the caps .the core of the plug was at a angle so they would not fire off the g strap yes i am sure it was a bad run on the plugs but it cost much $$ and time so i do not use them i am sure they can make good plugs. but they did not put them in them boats

Well I kept the AC Delco's I will put them in for now, I was told .040 was standard gap.. should I use .035 or .040, IMO Champion are JUNK

i don't know for sure but i believe at one time champion was second only to ac in sales, if ac is junk, and champion is junk, that don't say much for the rest of them. champion may have been #1 a few yrs. ago.

did you know what AC stand for?? alexander champion AC he was a scottish emigrate and they were made in flint mich i thing this is right

i agree on the champions being junk statement.... for me they've always run great for about 200-500 miles and then it'll start running like she needs a tuneup, but then i put a set of autolites in there and it'll run for 15,000 perfectly fine

well after this maybe I will go back and get autolites.. I did not know that ac delco is aka champion..

the only thing champion are good for is lawnmowers and chryslers..

Dave

your reasoning is, you have a chevy. that come with ac plugs, but now that you think champion which comes in Chrysler's, might be made by ac, so you rather use autolites, which comes in fords. i got it !!!
