This is a discussion on Brisk Silver Racing spark plugs for the 1.4T within the Eurocompulsion forums, part of the Dodge Dart Forum - Supporting Vendors category; I just noticed on Eurocompulsion's website that the recommended gap should be set to 0.020 versus the original 0.024.

I just noticed on Eurocompulsion's website that the recommended gap should be set to 0.020 versus the original 0.024. Smaller gap should clear up any breakup issues or misfiring. Also mentioned to drive spiritedly every 100 miles to bring the temp up to clean them. Should last a little longer. Anything I missed maybe Greg or Chris can add to this.
The Brisk plugs are a different style and after a discussion with Brisk they suggested that we use .020" due to their different design. We did that, and the engineers at Brisk were correct, it's better, especially at higher boost levels. So for the BRISK plugs we suggest and we use .020".
If you drive like a grandma the plugs may not get up to temp and thus may not self clean. To avoid this, Brisk recommends driving it in a spirited fashion at least once every 100 miles.
Alright! Great info!
I would check that plug regularly when you get it in there... At my last job I ran some of our high performance 12mm plugs and wore .010" every 1K miles. Loved the performance but couldn't stand the idea of regapping that often. Silver isn't a long-life plug material and these 1.4s eat anything that isn't really really quickly.
At EC we carry the stock plugs as well, but suggest the Brisk plugs for the more hardcore enthusiast. Allow me to explain:
The main advantage is that we are running one heat range colder with the Brisks which helps ward off knock. I am running 27psi and just made it all the way through the summer with these plugs and all that boost and didn't blow anything up. You can't get the OEM plugs one heat range colder so for me, this is how I see it, I would rather change spark plugs every 10k than an engine even once. The Brisks in my car have about 5k on them and are holding up very well with no issues.
Nice, maybe it was the high-discharge current that caused my plugs to wear so quickly... I got out of the business of designing and building spark plugs about 6 months ago(did it for 8 years) but I still like seeing what the market is doing.
The change in heat range is why the smaller gap feels better. Even the fine-wire stockers on a stock 1.4 with the stock gap will flash down the nose every once in a while and while that isn't a missfire it is far from optimal. More boost or a colder plug will make that issue even worse which a smaller gap will alleviate. We measured 25kV on my stock 1.4T under full boost and the stock coils would ring over at around 36kV if I remember right.
They are fine in cold weather. The plugs have two drawbacks. They are very sensitive to proper gap, and they don't last that long. The upside is they reduce the chance of knock, which is important on highly modded engines.
