A-Premium VVT Intake Exhaust Kit For GM Vehicles

This kit targets multiple GM lineage vehicles with 2.0L, 2.2L, and 2.4L engines. Best for owners who need a broad cross-reference with common OEM numbers. The kit references intake and exhaust solenoids with a variety of OE part numbers to aid cross-checking. Choose this if you own Chevrolet Equinox, Malibu, HHR, or nearby GM models and want a single kit to cover several fitments. Caution: verify exact engine code and year to avoid misfit on unusually configured engines.
HY-SPEED Exhaust Camshaft Actuator Solenoid Kit

Best for older GM trucks and SUVs with 4.2L or 2.8-2.9L engines in the Colorado, Trailblazer, Canyon, Envoy, and Hummer H3 families. This kit lists compatibility across a wide set of models from 2002 to 2012, making it a strong pick for builders with a mid-2000s GM motor. If you own a Trailblazer or Canyon with a 4.2L or 2.8/2.9L engine, this kit is a robust solution. Limitation: ensure the alignment of intake/exhaust solenoids to your specific engine code to avoid mis-match with rare trim levels.
VANUODA VVT Intake & Exhaust Actuator Kit

This kit provides broad GM coverage including Captiva Sport, Cobalt, Equinox, HHR, Malibu, Orlando, and Buick/Verano/Regal lines among others. It emphasizes both intake and exhaust solenoids with OE-number cross-references, which helps confirm fitment across multiple models. Best for owners who maintain several GM vehicles or who want a single kit that spans 2.0L-2.4L engines. Caution: verify the exact vehicle year range since some models are outside the common window.
ATRACYPART Intake & Exhaust Actuator Kit

Best for owners who want a detailed OE reference and broad engine compatibility across GM 2.0L-2.4L ranges. The kit includes both intake and exhaust solenoids plus camshaft position sensor references and crankshaft sensor references. Choose this if you prefer a kit with extensive part-number cross-references to minimize guesswork. Caution: ensure your VIN or engine code aligns with the included OE numbers to avoid a misfit on rare trims.
NewYall 4Pcs Engine Camshaft Actuator Solenoid

This kit targets GM family vehicles including GMC Acadia, Terrain, and Cadillac models across 2007-2016 years with 2.4L engines. It provides four solenoids covering intake and exhaust needs, with OE part-number references like 12586722 and 12615613. Best for owners who want a complete four-piece kit for both sides of the timing system. Limitation: coverage is strongest for GM 2.4L configurations; verify your engine code before ordering.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Match the kit’s listed engines (displacement and cylinder count) to your vehicle’s engine code and year.
- OE references: Look for cross-reference numbers (12655420, 12655421, etc.) to ensure correct fitment for your model.
- Intake vs exhaust emphasis: Some kits cover both solenoids; others may target one side more firmly. Assess whether you need intake, exhaust, or both for your maintenance goal.
- Cross-brand coverage: If you own multiple GM-family vehicles, a broad-spectrum kit can simplify future replacements.
- Installation notes: Check for any additional gaskets or seals typically included with the kit, and confirm the required tools for timing-system work.
- Warranty and returns: While not in product facts, consider the seller’s warranty policy and return window when replacing critical engine components.
Frequently Asked Questions
- What is a camshaft position actuator solenoid kit used for?
It replaces failed intake and exhaust solenoids that control variable valve timing, helping restore proper engine timing and performance. - How do I know which kit fits my GM vehicle?
Check the vehicle’s engine displacement, model year, and the OE part numbers listed in the kit description to match your exact fitment. - Can I install a non-OE kit on my car?
It can be possible, but alignment with engine codes and cross-reference numbers is crucial to avoid timing or fitment issues. - Are these kits suitable for modern Mercedes-Benz engines?
The listed products focus primarily on GM-based vehicles; some A-Premium items include broader cross-compatibility, but verify model-by-model for Mercedes fitments prior to purchase. - Should I replace both intake and exhaust solenoids at once?
Replacing both is commonly recommended if both sides show symptoms or if your timing system is in poor condition to ensure balanced operation. - What are common symptoms of a failing camshaft actuator solenoid?
Symptoms include rough idle, reduced power, check engine light, and hesitation during acceleration, all of which may point to timing control issues.
