While many of us remember the days of tapping your spark plugs on the work bench to get the perfect gap, the high-performance spark plugs we use for our Cadillacs today require much more finesse. That’s why we’re now offering our Tapout Tuning Spark Plug Gapping Tool and Feeler Gauge Set!

This spark plug gapping tool allows for precise gapping with no risk of spark plug damage. Feeler gauge set has 32 blades ranging from .0015 to .035”, including all the common sizes used in high performance Cadillacs (.035”, .028”, .026”, .024”, .022”, .020”, .018” and .016”).

Now you can be sure you get the perfect gap on your spark plugs every time. Pair that with plenty of dielectric grease upon their installation and you’ve set yourself up for success!

If you’re running a stock driveshaft on your ATS-V or CTS-V, the JXB Performance Driveshaft Center Support is going to be your best friend! The stock center support bearing carrier holds the driveshaft in place with a layer of thin rubber. It doesn’t keep the bearing centered well under load, allows the bearing to sag over time and ruin the driveshaft alignment, and creates slop in the driveline during shifts and throttle application. Over time the OEM bushing sags and becomes brittle, eventually dry rotting and cracking.

This upgraded unit keeps the driveshaft firmly in place at all times, and its solid construction ensures it will never sag or crack over time. The thick bushings ensure the driveshaft cannot move from center, maintaining driveshaft alignment at all times.

These are available with bushings to accommodate street use (softer and quieter) and track use (harder and louder). Or you can get one of each, so you’re covered no matter what!

Normally available for $299.99, these are currently available for pre-order at $249.99! First production run will ship January 2024.

We are happy to announce that Xtreme-DI fuel injectors for ATS-V and CT4-V Blackwing applications are now in stock for immediate shipment! These injectors start as brand new OEM Hitachi fuel injectors and are modified to flow 50% more fuel than stock. They are flow tested and matched in sets of six to flow within 0.5% of each other. They maintain stock idle characteristics, are perfectly linear and remain rock solid, even at 3,000 psi! These injectors provide drop-in fitment, with no adapters or pigtails required.

Every Xtreme-DI fuel injector set gets tested and matched at three different operating points and comes with full documentation:

–  0.8 ms. @ 290 psi (20 bar) for idle stability
–  10.0 ms. @ 1,450 psi (100 bar) for static flow reference (qstat)
–  6.0 ms @ 2,900 psi (200 bar) for WOT performance and stability

Please note that custom tuning is required for these fuel injectors. As the premier LF4 tuner worldwide, we will be happy to help in this area. You can find more details on our Remote Tuning services for the ATS-V and CT4-V Blackwing on TapoutTuning.com.
