Sold in sets of 6.
These are the OEM spark plugs for your Cadillac ATS-V (LF4) or CTS V Sport (LF3).
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 GM at a gap of .035".
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.
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.
