This is a set of 6 Brisk Silver Racing spark plugs for the LF3/LF4 engine. These are 1 step colder than stock.
We offer our plugs to come pre-gapped for your builds needs if you so choose. Stock will be how the plugs come shipped from Brisk at a gap of approximately .032".
The Stage 1 offering, gapped at .025", is for stock or mildly modified cars running pump gas 91 or 93 octane.
The Stage 2 offering, gapped at .020", is the go to gap that we run on all of our ZZP ATS-V's. Stage 2 is for full bolt on cars on E85, max effort stock or aftermarket turbos, or those cars that have previously had ignition related misfires under load.
Brisk Silver Racing Spark Plugs have a smaller diameter silver core and conventional open spark hook type earth electrode give an outstanding performance in igniting high octane fuel mixture associated with alternative fuels like CNG, LPG, Propane, E85 blend, Alcohol, LNG, Race Fuels and Nitro.
Silver metal is the single best material for a spark plugs core electrode, as it can dissipate heat fast, resulting in overall lower spark plug temperature and a more powerful spark.
The stronger the spark the faster and better the flame front and flame speed giving smother higher RPM range in engines.
Heat range: 12 (Same as NGK 8/Denso 24)
We highly recommend filling the ignition coil boots with dielectric grease during installation to prevent carbon tracking. ATS-V's and LF3/LF4's in general require frequent maintenance when it comes to the ignition system, we recommend changing plugs approximately every 10-15k.
Fits: 2016-2019 Cadillac ATS-V, 2014-2019 Cadillac CTS V-Sport, 2016-2019 Cadillac XTS V-Sport, and 2022+ Cadillac CT4-V Blackwing.
