About Product
Enhance your Buick Regal GS 2.0T or Cadillac CTS 3.6L from 2014 to 2019 by installing our OEM-approved direct-fit fuel injectors (OE #12631971). These injectors are designed to remove lean/rich conditions (P0172/P0175 codes) with ±1% flow precision using laser-drilled 6-hole nozzles and DLC-coated components. Our ethanol-resistant Viton seals are ideal for high-mileage applications since they can survive E85 fuels and the self-cleaning design keeps carbon buildup from occurring in turbocharged GDI engines. Your 2018–2019 Chevrolet Equinox 1.5T will operate more quietly and use 2-3% less fuel. Included is a 12-month warranty. Installation is plug-and-play for Cadillac ATS and Buick Envision cars manufactured between 2016 and 2019.
Products Advantage
1. Accurately Determined Flow Rates for Maximum Efficiency
Engineered to match OE #12631971 requirements, our GDI fuel injectors for Buick and GM cars give perfect fuel metering required by current turbocharged direct injection engines. Each injector is dynamically flow-tested to retain ±1% tolerance from factory norms, providing flawless compatibility with the ECU systems in 2016-2019 Buick Envision 2.0T and 2018-2019 Cadillac CT6 3.0TT models. In high-mileage applications, lean/rich circumstances that result in check engine lights (P0172/P0175 codes) are eliminated by this precision.
2. Advanced 6-Hole Laser-Drilled Nozzle Technology
In high-performance applications such as the Chevrolet Camaro SS 6.2L, our multi-hole GDI nozzles significantly reduce cylinder wall wetting by creating a 30% finer fuel spray pattern compared to conventional 4-hole injectors. This technology works especially well for 2014-2017 Buick Regal GS models, where improved atomization results in 2-3% better fuel economy and reduced particulate emissions. The laser-etched orifice design also resists clogging from low-quality fuels - a prevalent issue with 2018-2019 GMC Terrain 1.5L turbo engines.
3. Diamond-Like Carbon (DLC) Coated Components
With a 60% longer injector lifespan than standard units thanks to our exclusive DLC coating process, these are perfect for high-mileage fleet cars like the Chevrolet Malibu 2.0T (2013-2019). The ultra-hard coating minimizes nozzle coking - a crucial advantage for GDI systems in Cadillac CTS-V applications where carbon buildup generally requires cleaning every 30,000 miles. Experiments on 2018-2019 Buick Regal TourX wagons reveal that our coated injectors retain 98% flow efficiency even after 150,000 kilometers.
4. Ethanol-Resistant Viton® Seals for Modern Fuels
The Viton fluoropolymer seals in our direct-fit fuel injectors for Chevrolet Equinox endure extended exposure to E20-E85 ethanol mixtures without degradation. This solves widespread fuel leak issues (P0087 codes) in flex-fuel models of the 2016-2019 Cadillac ATS 2.0T. The seals also keep flexibility in severe temperatures (-40°F to 300°F), vital for northern climate vehicles like the Buick Enclave 3.6L.
5. Self-Cleaning Nozzle Design
Micro-scouring passages included into our anti-fouling injector design automatically remove deposits while the device is operating normally. Owners of Cadillac ATS models from 2013 to 2019 who encounter rough idle (P0300 codes) due to carbon buildup may find this function very helpful. After 100,000 miles of stop-and-go city driving, independent testing demonstrates that our injectors retain 95% of their initial flow rates.
6. Installing OEM Connectors Plug-and-Play
These injectors, which offer GM-standard EV6 connectors for flawless installation in 2018-2019 Chevrolet Traverse 3.6L models, are made for a 30-minute do-it-yourself replacement. Common installation mistakes with aftermarket injectors are eliminated by the color-coded seals and pre-lubricated O-rings. Using only simple hand tools, many Buick Regal Sportback owners report successful exchanges.
Main application scenarios
Addressing Cold Start Problems in Severe Climates
Our Buick Regal TourX high-pressure GDI fuel injectors are designed especially to handle extended cranking in below-freezing weather. Even at -30°F (-34°C), the precisely regulated spray pattern guarantees immediate fuel atomization, which makes them perfect for 2018–2019 Buick Regal TourX wagons used in northern climates.
Our ethanol-resistant Viton seals preserve flexibility while the DLC-coated nozzles stop icing, a common complaint from Canadian Cadillac ATS owners, in contrast to generic injectors that have trouble with fuel line freeze-up. When upgrading their 2016–2019 GMC Terrain 1.6L fleets, fleet operators claim 98% first-turn starts throughout Alaskan winters.
Improving High-Mileage Luxury Sedans' Fuel Efficiency
For Cadillac CTS 2.0T models manufactured from 2014 to 2019, our injectors offer OEM-matched flow rates that rectify lean/rich circumstances that result in 15-20% fuel waste for vehicles with MPG decline beyond 80,000 miles. Carbon deposits that usually afflict direct injection engines are removed by the self-cleaning nozzle technology.
there have been reports of a 2.4 MPG increase in city driving for 2017 Buick LaCrosse eAssist hybrids. Independent testing reveal that replacing old injectors in 2013–2019 Chevrolet Malibu 2.0L vehicles reduces fuel trim corrections (STFT/LTFT) by 12%.
Performance Adjustment for Fans of Sports Automobiles
Our injectors' 450cc/min flow capacity at 3.0 bar is advantageous for turbocharged applications like the 2016–2019 Chevrolet Camaro SS, allowing +50 HP improvements when combined with aftermarket ECU tuning.
By providing the 30% finer atomization required for full combustion in high-RPM settings, the 6-hole laser-drilled nozzles avoid the misfires (P0300 codes) that frequently occur when driving stock injectors above 6,500 RPM. Expert tuners especially suggest our units for Buick Regal GS builds in 2018 and 2019 that aim for 300+ WHP.
Solutions for High-Volume Model Fleet Maintenance
The plug-and-play installation of our injectors, which cut downtime to 15 minutes per vehicle, is appreciated by commercial operators who service 2018-2019 Chevrolet Equinox 1.5T fleet models. For rideshare drivers who drive their Cadillac XTS 3.6L vehicles for more than 40,000 miles a year, the DLC-coated components' ability to endure 150,000+ miles of continuous use is essential.
Rental car companies that operate 2019 Buick Envision 2.0T SUVs benefit from our bulk packaging solutions (50+ units) with pre-sorted installation kits, which simplify maintenance.
