Product details
VOUVOU offers this cylinder head gasket for Haima applications with the 474Q motor. The five photos show a dark gasket with four large openings, featuring peripheral passages of various shapes. Reference 474Q-10-271 serves as a reference to select the part corresponding to the motor.
Recognize the shape of the cylinder head gasket
The gasket is placed between the motor block and the cylinder head. Its openings must match the cylinders, the mounting hardware, and the passages designed in this assembly. The front and diagonal views allow you to compare the contours, the elongated cutouts at the ends, and the distribution of the small drillings.
The stated material is steel. The visible black appearance is not enough to identify the coating composition, the number of layers, or the compressed thickness. These parameters must match the planned repair, especially if the motor has already been resurfaced.

The three choices below repeat the labels retained in the catalog. The two-piece variant corresponds to a quantity of gaskets, not a complete motor gasket kit. No cylinder head bolts or other gaskets are stated to be included in the contents.
The OEM copy mention is a supplier label: it does not guarantee an original Haima part, homologation, or a higher quality level. No measured technical difference between the China and OEM copy variants is provided. The photos are not individually attributed to these choices.

The description cites Haima 2, M3, S5, and M5, with motor code 474Q. It does not provide the years, displacements, or any motor indices. Before ordering, cross-reference the VIN, the complete motor code, the reference sought, and the gasket passages with the vehicle documentation.
VOUVOU presents itself in its documentation as a distributor of parts for Mazda and Haima. The general list of Mazda vehicles describes its activity; it does not constitute a compatibility list for this 474Q-10-271 gasket.
The technical guide Elring dedicated to cylinder head gaskets explains that the required surface quality depends on the gasket construction. The workshop must therefore check the gasket surfaces and choose the appropriate part before installation. It must also search for the cause of the failure, then apply the tightening sequence and the visserie prescriptions specific to the motor: no specific torque for the 474Q is provided here.

Frequently asked questions
Does reference 474Q-10-271 correspond to all the Haima models listed?
The source lists Haima 2, M3, S5 and M5 with motor 474Q, without specifying years or indices. The model alone is not enough: check the VIN, motor code and the required seal reference.
What does the 2-piece China variant contain?
It announces two cylinder head gaskets. These are not a complete engine gasket kit, and these two parts must not be stacked to adjust the thickness during assembly.
Does OEM copy mean original manufacturer part?
No. This description belongs to the supplier and does not establish a Haima origin. The specification sheet does not include technical characteristics that differentiate this variant from the China variants.
What is the thickness of the seal?
The thickness, including the compressed thickness, is not specified. It must be confirmed for the relevant assembly, particularly when the block or cylinder head has been resurfaced.
Do the photos allow you to choose the variant?
They show the contours, the four large openings, and the holes of the seal. They are not individually connected to the three variants and do not allow assigning a different construction to each.
Are the cylinder head bolts included?
No screw set is specified. The workshop must provide the required mounting hardware and apply the replacement and tightening specifications for the relevant motor; no tightening torque can be inferred from the photos.
