Splitfire Plugs vs. Standard Plugs

Okay, so is there really a difference in using Splitfire Plugs or even Splitfire Triple Platinum Spark Plugs as opposed to any regular run-of-the-mill spark plug? Thanks.

The answer, in my recently educated opinion, is no for the most part.

I recently used the Bosch +4's, basically the same "gimmick" as the splitfire plugs. After several debates, one with Jerry B. , I decided to try the single platinum plugs by Autolite.....which many here use.

I have better results with the singles , than I did with the +4's. I also have a FireControl Iginition, which does make a difference and that is true.....but as for the plugs, just stick with the single platinums by Autolite or similar make...take it from a recent turncoat from the "splitfire" hype.

Oh and prepare yourself, the debate will begin shortly. Have plenty of popcorn and soda.....I mean beer.



RE 3.5 and all kinds of other relevant goodies, you know winch and stuff.

I agree with you...just use the correct heat range plug and don't bother with the splitfires or any of the gimmicky plugs. I tried the Splitfire triples in my Camaro. I put them shortly after I first installed the engine (I ran with AC/Delcos first)...no difference in performance, MPG, etc. When I installed the MSD I ran with the splitfires for awile and then went back to AC/Delco's...again no difference (there was a difference going to the MSD, but none upon switching plugs).

I just use Champions (in our Jeeps) and AC/Delco's in the Camaro.

Splitfire sparkplugs are junk.

I am currently running Bosch Platinum 4s and they perform about identical to the copper champions that were in there before. The spark plug choice isn't that important in a stock jeep motor, I would just run champion or ngk coppers and change them every 10k miles if I was to do it again. The copper plugs produce just as good if not a better spark than platinums, they just don't last as long.

Spark becomes important when you are running a high performance motor and trying to avoid blowout. I run ngk coppers in my twin turbo stealth because that is what has proven to give the least blowout problems at high boost levels, they give better spark than platinums or iridiums, you just change them 3 times as often

Cheap, Capable, Reliable.......

Copper will always produce a better spark, which makes more power. Copper has better conductive properties than platinum and iridium.

Split Fire's aren't junk plugs, they just aren't worth the money.
