To put it straight, this is a dedicated piston for the Haima S7, with the part number SA00-11-102M1. No need to memorize those fancy terms—let me break it down for you simply:
It’s made specifically for Haima S7 models from 2010 to 2016. Whether it’s the 1.8T (that HM484Q-T engine) or 2.0L (HM484Q-A) version, this piston works.Its size is exactly the same as the original—like, the piston diameter is 84mm. When you install it, it fits perfectly tight in the cylinder with no air leaks. The part number SA00-11-102M1 is factory-certified, so you can just swap out the old piston for this one—no modifications needed.
Great power performance: The compression ratio matches the original factory specs, so fuel burns more fully. It’s responsive when you hit the gas—no lag even with frequent starts and stops in traffic.
Reliable, no hassle: It can handle the 1.8T engine’s high torque (230N・m) and won’t break easily. The surface coating also reduces engine noise and vibration.
Saves money and trouble: The good sealing means it doesn’t waste oil, and it even cuts fuel use by 5%-8%. With normal use, it lasts over 200,000 km—no need for constant trips to the repair shop.

Haima S7 Piston SA00-11-102M1 Features
1. Perfect fit for Haima S7
It’s made just for 2010-2016 Haima S7, works for both 1.8T (HM484Q-T) and 2.0L (HM484Q-A) engines. Size matches the original (84mm diameter), fits tight in the cylinder with no air leaks. The SA00-11-102M1 part number is factory-approved, so you can swap old pistons directly—no tweaks needed.
2. Solid material
Uses high-strength aluminum alloy—tough enough to handle engine heat/pressure without warping, yet light. Also dissipates heat fast, so it lasts longer.
3. Smart little design touches
Oval-shaped skirt cuts down friction.
Surface has Grafal-like coating to reduce wear and make lubrication smoother.
3 grooves (2 for gas sealing, 1 for oil control) + a wear-resistant cast iron ring in the first groove—stops oil/gas mixing, hard to break.
4. Practical performance
Matches original compression ratio: fuel burns fully, responsive acceleration (no lag in traffic stops/starts).
Saves oil and gas: good sealing means no oil waste, cuts fuel use by 5%-8%.
Quieter and smoother: surface coating reduces engine noise and vibration.
5. Durable & hassle-free
Can handle 1.8T engine’s 230N・m torque—won’t break easily. Normal use lasts over 200,000 km, so no frequent repair trips.

Summary: Haima S7 Piston SA00-11-102M1
Plain and simple—this piston’s made just for 2010-2016 Haima S7 (works for both 1.8T and 2.0L engines). It fits like a glove with original specs (84mm diameter, no air leaks), swaps directly with the old one (factory-approved SA00-11-102M1 part number).
It uses tough, lightweight aluminum alloy that handles engine heat/pressure and cools fast. Smart designs (oval skirt, Grafal-like coating, 3 grooves + cast iron ring) cut friction/wear and keep oil/gas separate.
In use, it boosts response (no lag in traffic), saves 5%-8% fuel + no oil waste, runs quieter/smoother. It’s durable too—handles 1.8T’s 230N・m torque, lasts over 200,000 km, and means fewer repair trips.
