are you saying there is no truth to my statement? thats just my experience,, ive done it a few times on my dyno and its always worth power
in a ss hemi gained 10 in a ss 427 chevy gained 10 in a pump gas small chevy gained 6 in a 480 cubic inch fe pump gas was worth 8 in a 505 bb mopar pump gas was worth 6
all average power numbers which is all i ever look at
so i built a small blk ford motor for a guy local who works for the prince of quatar(alanabi guy),, so he is hooked up with shannon jenkins from some nitrous company,, i told my customer to run autolite plugs but they didnt cause they later told me i didnt tell them a part number,,, so they ran ngk,, so they went down south and shannon told them to go to the store and get some autolite plugs cause they make more power than ngk plugs,,, so they did cause they were told to by two totaly different sources. its a 360 cubic inch 8.2 deck ford with tfs heads in a 2900lb car, clutchless 5 spd,, nitrous,, been 7.80's at 180something

i will believe that there might be a minisque diff in some plugs as in heat range tips lenghts , ets but to come make bold statements that this plug will make more hp than the same equivalent plug from diffrent plug manufacture , is totally without merit , now if youre testing a totaly diffrent plug vs a racing style plug with diffrent heat range , then i will believe some of youre statement! other than that, show me dyno results with no other changes than that of a plug change, using the same indexing , timing, etc just a plug change thats all ,, lets see the results!!

I have a hard time believing this to but hopefully he's right that will be the cheapest horspower I have made in a while
Horse power TV always makes that type of power increase with the plug of the month

This was replacing and old set with new AR's & new NGK's? or were you replacing the NGK's with AR's?

i have bbeen running the NGK R5671A-9's for yrs.. if Jeff says they are worth an improvement..thats good enough for me.. i agree the chrome/nickle base is easier to read then the black phosfate. i think they have a nickle version fwiw...i just dont know the part number..
what # Autolite plug is a direct cross match from the NGK R5671A-9 plug?
365" Iron J heads,,3480lbs best 1.39 60ft on SS springs.10.54,124 mph ...6.67 1/8th et.average 60fts 1.46 w/ small cam &.063 no2 pill tagged & insured [image][/image]

no this was with the Indybrocks with the motor at 12.5-1 and that was install brand new NGK's made 1 pass then installed brand new AR 3911. The test was done because my machinist swears by the Ar's
I'm trying to figure out what plug to run in my W-5s for my drag week car, 11:1 ... I've been using Champion race plugs for my W-9 but they are pretty pricey
