You might want to edit the first post with this information.Just want to clarify that I initiated the test done by JustSpeed7 yesterday in order to confirm any gains from a more proper test as requested. It turns out that I made the mistake of comparing dyno results between factory plugs with 15k and an unverified gap to a new set of Brisk Silver plugs one heat range colder that were pre-gapped at .032" from the factory. My apologies for the inaccurate results and I'm glad we were able to run this test and that things have been clarified.
The only reason I was so sure that the original results were legitimate is because my friend who own's the shop/dyno I use for testing has a 2011 F150 Ecoboost and also had great results from using the Brisk plugs so I didn't have any doubts. They also ran them on a 7-sec twin turbo Coyote powered Mustang with impressive results.
Yeah he did that...did you not see his postI saw .003 wear on my stock plugs in 13,500 miles so I think it might make a difference. please retest with brand new stock plugs.
Ok so the results are in I took your guys advice to help see the exact gains on the plugs, so I bought a set of brand new Motorcraft plugs yesterday and this morning brang those along with the brisk plugs to do the pulls.
We changed to the new Motorcraft plugs gapped at .32, then did two pulls and then changed to the Brisk Racing plugs and did two more pulls and here was the outcome of the runs.
