If you want a complete 3-piece powertrain solution for your 2019-2024 Mazda 3 or CX-30, choose PATEWIN Engine Motor Mount; if you need a full 4-piece stabilization kit specifically for a 2010 Mazda 3 2.0L, choose YEOPGYEON 4PCS. This isn't a close call where the answer changes based on the weather or the time of day. The decision comes down entirely to which vehicle you are driving and which year it was built. These two products serve completely different generations of the same car line, and mixing them up is impossible without causing mechanical issues.
For teen drivers who might be inheriting an older family sedan or buying their first used car, understanding this distinction is critical. A young driver in a 2010 model cannot install the newer mount kit designed for the 2019-2024 models, and vice versa. You must match the part number exactly to the engine bay geometry. Below, I break down exactly what each set offers based on the engineering specs and design features available to us, so you can stop guessing and start fixing that rattle or vibration.
• PATEWIN Engine Motor Mount: Offers a targeted 3-piece set with high-strength carbon steel brackets specifically engineered for 2019-2024 Mazda 3 and CX-30 L4 engines, but it only covers right, left, and rear lower points.
• YEOPGYEON 4PCS: Provides a comprehensive 4-component system including four distinct mounts (A4402, A4405, A4421, A4418) tailored exclusively for the 2010 Mazda 3 2.0L, offering broader coverage for that specific chassis.
• Best For: Choose PATEWIN if you own a newer generation Mazda 3 or CX-30 with automatic transmission; choose YEOPGYEON if you are restoring or repairing a 2010 Mazda 3 2.0L.
The PATEWIN Engine Motor Mount is a precision-engineered solution designed for a very specific window of automotive history: the 2019 through 2024 era of Mazda 3 and CX-30 vehicles. If you drive one of these models equipped with either the 2.0L or 2.5L L4 engine, this kit is built to address the unique dynamics of that modern powertrain. The design focuses heavily on eliminating steering wheel tremors and chassis resonance that often plague these cars at idle. It achieves this by utilizing rubber insulators specifically tuned to absorb kinetic energy from the L4 engine block.
This product is ideal for owners dealing with clunking sounds during sudden acceleration or when coming to a hard stop. Worn supports on these newer models frequently lead to excessive engine pitching, which throws off drivetrain alignment. The PATEWIN kit secures the engine firmly to the chassis using high-strength carbon steel brackets. This material choice is not arbitrary; it is necessary to support the weight and torque output of the modern 2.0L and 2.5L engines while ensuring the steel-to-rubber bond maintains structural integrity over time.

You should buy this set if you need a complete repair for the primary support locations of your L4 powertrain. The kit includes three essential components: a Right Engine Mount, a Left Transmission Mount, and a Rear Lower Engine Torque Strut Mount. However, you should skip this option if your vehicle is anything other than a 2019-2024 Mazda 3, CX-30, or Mazda 3 Sport with an automatic transmission. The mounting geometry and bolt patterns are too different for older or manual transmission models to accept this unit safely.
The YEOPGYEON 4PCS set is a dedicated restoration package for the 2010 Mazda 3 2.0L. Unlike the newer PATEWIN kit, this is a four-component system designed to provide coordinated support for both the engine and transmission across the entire subframe. It addresses the specific harmonic frequencies generated by the 2.0L engine found in this older generation. The goal here is to reduce cabin noise and promote a more refined interior environment by dampening steering wheel tremors and idle vibrations effectively.
This product is perfect for owners of the 2010 model who are experiencing "clunking" sensations when shifting between Reverse and Drive. By securing the transmission housing, the YEOPGYEON mounts help maintain consistent drivetrain alignment, which directly translates to smoother shifting performance for automatic transmissions. The construction relies on reinforced materials, including high-strength steel brackets and heat-resistant rubber compounds. These are engineered to resist premature cracking and degradation, a common failure point in compact engine bays exposed to extreme thermal stress.
I recommend this set for anyone looking for a direct-fit installation that follows the precise mounting geometry of the 2010 subframe attachment points. The kit includes four specific units: A4402, A4405, A4421, and A4418. This ensures that every critical point of the powertrain is stabilized simultaneously. However, if you have a 2019 or newer Mazda 3, or any vehicle with a 2.5L engine, this kit will not fit. The dimensions and bolt configurations are exclusive to the 2010 2.0L architecture, making it a specialized tool for that specific year and displacement combination.
• Best for 2019-2024 Models → PATEWIN Engine Motor Mount (Only fits 2019-2024 Mazda 3/CX-30 with 2.0L/2.5L).
• Best for 2010 Models → YEOPGYEON 4PCS (Only fits 2010 Mazda 3 2.0L).
• Best for Drivetrain Alignment → Both offer excellent alignment support, but PATEWIN uses carbon steel for higher torque loads while YEOPGYEON uses heat-resistant compounds for thermal stability.
• Best for Complete Coverage → YEOPGYEON 4PCS (Includes 4 distinct mounts vs. PATEWIN's 3-piece set).
• Best for Steering Wheel Tremor Reduction → Both utilize synthetic rubber dampers, but YEOPGYEON is tuned for 2010 harmonic frequencies while PATEWIN targets modern L4 resonance.
• Best for Heavy-Duty Structural Integrity → PATEWIN Engine Motor Mount (High-strength carbon steel brackets designed for larger torque).
• Best for Direct-Fit Installation → YEOPGYEON 4PCS (Engineered for precise 2010 subframe attachment points).
• Best for Teen Drivers in Older Cars → YEOPGYEON 4PCS (Often found in entry-level used inventory from the 2010 era).
In my opinion, the choice is strictly dictated by your vehicle's manufacture year, and there is no middle ground here. If you are a teen driver sitting in a 2010 Mazda 3, the YEOPGYEON 4PCS is the only logical path forward because it covers all four critical mounting points required for that chassis. Conversely, if you are behind the wheel of a 2020 Mazda 3 or CX-30, the PATEWIN Engine Motor Mount is the superior choice due to its carbon steel construction and specific tuning for the L4 engine's torque characteristics. Do not attempt to cross-reference these parts; they are incompatible by design. Pick the one that matches your VIN, and your ride will feel significantly smoother.
No, both the PATEWIN and YEOPGYEON sets are explicitly designed for automatic transmission models only. Attempting to install them on a manual transmission vehicle would likely result in incorrect fitment and potential drivetrain damage.
PATEWIN utilizes high-strength carbon steel brackets optimized for the torque of 2.0L and 2.5L engines, whereas YEOPGYEON focuses on heat-resistant rubber compounds and steel to withstand the thermal stress typical of the 2010 compact engine bay.
Yes, both products are engineered to minimize "clunking" sensations. They secure the transmission housing and maintain drivetrain alignment, which directly addresses the excessive movement that causes noise during gear shifts in their respective model years.
No, the YEOPGYEON kit is strictly for the 2010 model with a 2.0L engine. The mounting geometry and part numbers (A4402, A4405, etc.) do not align with the 2019-2024 chassis, so it will not fit.
