Drivetrain BRISK spark plugs - first impressions

BRISK spark plugs - first impressions
Just replaced a set of 5K old NGK Iridiums with the Brisk Racing Silver Plugs. (single electrode, DR12S)
First off, they MUST be re-gapped as they come out of the box at about .015
I gapped them to .028
First thing I noticed was a faster cold start-up. The high speed miss and hesitation I had with the NGK's is gone. (Even when new, I had a miss with the NGK's)
So, they did what I had hoped they would do so I'm a happy camper!

Jan threw in a set for me on my JCW when I got his tune done in Seattle. He really likes them so that's good enough for me
After the initial tune my gain was approx 9hp, then a change out of my stock JCW plugs with only 10K but had been running lean for that mileage, in go the Brisks and some more of Jan's tweaking magic and yet another 9hp!

I also gave Brisk plugs a try, but didn't want to comment on them until I had some solid before/after seat time. Of the two track days I did this autumn, the first was with my usual NGK BKR8EIX. The NGK's have significantly better throttle response than the stock plugs, but with their aggressively cold heat range, they offered a bit of a chunky and sluggish cold-engine response.
I installed a set of Brisk DR12YS, which are the equivalent heat range. Like Jim found, out of the box their gapping was horrid. I gapped them to 0.030", because that sounded reasonable at the moment. The results were clear upon first start-up. Smoother revving during cold operation, and even crisper and quicker throttle response at all times. On the track, however, is where these expensive plugs really surprised me. I was able to very smoothly modulate the throttle on corner exit, something I always found a difficult operation with the Tritec engine with the stock bypass valve. Somehow these plugs smoothed out that behavior and allowed me to focus on driving and not wrestling with the engines old quirks.
Two thumbs up from me. They surely suprised me with their clear effectiveness.
Cheers,
Ryan

I have never, ever screwed a spark plug into any car I've owned without checking the gap. Like I said, the Brisk plugs came out of the box at around .015. One was actually almost totally closed. I also noticed that of the four plugs, only one had a protective plastic cap over the electrode end. (I got mine from Alta, also)
Another thing, make sure the connectors at the top end of the plug are screwed on tight. Mine were all loose.

the 4 prongs don't need gapped but every one I have checked of the DR-12s are not gapped properly
