Fitment

• 2016–2019 Cadillac ATS-V, 3.6L LF4 twin-turbo V6.
• 2014–2019 Cadillac CTS V-Sport, 3.6L LF3 twin-turbo V6.
• 2014–2019 Cadillac XTS V-Sport, 3.6L LF3 twin-turbo V6.
• 2022 onward Cadillac CT4-V Blackwing with 3.6L LF4 twin-turbo V6, subject to exact-year and original-part confirmation.

The supplier labels the last application “CT4-V”; this listing limits it to the 3.6L LF4 Blackwing application, not the regular CT4-V. Confirm engine code, original throttle-body part number, and connector before ordering. CTS V-Sport is not CTS-V, and this listing does not claim CTS-V compatibility.

Features

• Optimized active contours and ported upstream bore with velocity stack.
• Diamond-polished 16 Ra microinch surface finish.
• Shaftless high-pressure side of the blade for increased wide-open-throttle flow area.
• Dome and thread-locked screws.

Soler states that tuning is not required. Designed to improve throttle response; no specific horsepower gain or vehicle manufacturer warranty protection is promised.

Choose your order type
