Brisk spark plug replacement interval?
Anybody know how long brisk racing spark plugs are supposed to last? My fuel mileage has been a bit lower than normal lately, and my car has an occasional stumble, so I’m kind of wondering if maybe a new set of plugs would help, but I don’t want to blindly throw $50 at the problem. I have a mostly stock car with a 17% pulley and the plugs have roughly 30,000 miles on them. It seems like the stock ngk plugs are supposed to be good for 50,000 miles, but I can’t remember for sure.

I am gun shy with most precious metal unless the vendor/manufacturer can justify to me in scientific evidence the much touted "benefits". I bought a cooler set of NGK's OE replacement after 15% pulley installation. Soon I realized the reasons of the quad ground electrodes , and I switched to the cheaper lowly copper plugs circa $1.50 each instead. No negatives noted driving or over-driving on track.
Truth be told, I don't own a gold Rolex nor forged bling wheels that my driving doesn't need.

I'm using the BRISK LGS-T plugs in TRACKRAT and, as I understand it, the recommended change interval is something like 10,000 miles. For me, that's a whole lot of track miles so I don't mind changing them, considering what I spend on fuel, tires, registration fees, lodging and food! FWIW, they've given me excellent results.

I like how a "performance" vendor present "scientific" proofs of why their fancy pants boutique product is better. On their site they showed the graphs of superior thermal and electrical conductivity of silver they use against the lowly copper.
My immediate question what is the size of their silver electrode compared the no-thrill NGK baseline copper plug? Also at the ungodly combustion temperature and thermal energy, does the fine-hair splitting make any discernible performance difference? Oh, silver is only the entry level of their lineup. There are many more precious metal plugs that they are happy to take your money. I too spend obscene amount of money for each track day, but I value my hard earned money, down to a cent. I do not subscribe to poser performance products.

If you don't replace the plugs what else is open to you?
Has the behavior persisted over the span of several tanks of fuel? Could you have gotten a batch of bad/stale gasoline?
How's the engine air filter?
Fuel filter?
Are these due or past due to be changed?
In some cases running a bottle of system fuel cleaner may help. I don't know what's available where you are but I likeTechron. Use it according to directions on the bottle. When the fuel level gets low do a repeat treatment. Drive the car until most all of the 2nd tank of fuel treated with Techron is used up. It is best if after you use this stuff you do an oil/filter service. The Techron can contaminate the oil and you don't want to continue to leave that oil in service.

The thread mentioned by pnwR53S about spark plugs is a great primer and a good read,
it is here:

It was reading that thread which convinced me to save my money on pricey plugs and go with NGK BKR7E --- they've performed faultlessly for me on an 06 JCW.

With 30k miles on them for sure I'd replace them. We don't use the brisk in our shop as we find them to wear out much faster so I'm kinda surprised you got 30k on them. I'd go back with the JCW platinum plugs as we find them to last the longest and not come loose like some others.
