Soler Performance SE4590-76 modified OEM throttle body for Cadillac 3.0L twin-turbo LGW/LGY V6 engines, with a 72 mm nominal bore and 76 mm effective flow configuration. Choose a new unit, refurbished core exchange, or send-in rework service.

Fitment

• 2016–2019 Cadillac CT6 equipped with the 3.0L LGW twin-turbo V6.
• 2020 onward Cadillac CT5 and CT5-V equipped with the 3.0L LGY twin-turbo V6, subject to exact-year and original-part confirmation.

Engine-specific fitment only. Confirm engine code, original throttle-body part number, and connector before ordering; the vehicle name alone does not establish compatibility. Not a listing for other engine options or CT5-V Blackwing.

Features

• Optimized active contours and ported upstream bore.
• 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. Professional installation is recommended because access to the original throttle body can be difficult.

Choose your order type

• New unit: brand-new OEM part reworked by Soler, $440 standard warranty or $469.99 with extended warranty.
• Core exchange: refurbished, reworked OEM unit, $440 including a $100 core deposit, or $469.99 with extended warranty. Soler states that the deposit is refundable when your unmodified OEM core is received within one month of delivery. Confirm return instructions and refund handling before ordering.
• Rework your own: send-in service, not an additional new throttle body, $325 standard warranty or $354.99 with extended warranty. Send your unmodified OEM unit for rework. Soler quotes 1–2 business days for rework after receipt, excluding shipping; this is not a delivery guarantee. Contact Soler first for an already modified or ported unit.

Supplier lists a 1-year standard warranty and an optional 3-year extended warranty at $29.99 extra. Supplier terms apply. Coordinate core returns and send-in service before shipping parts.

Part-number clarification: the supplier option-label text references SE0983-70, while this page and its actual variant SKUs identify SE4590-76. This listing retains the actual SE4590-76 variant SKUs. Confirm the ordered part number with Soler before fulfillment.
