OE 35399-2S133 — Injector Service Kit for Hyundai

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Incoming batches pass a dimensional check, a material look-up against the engine & fuel system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

OE 35399-2S133 is the factory reference for this injector service kit on selected Hyundai models. The Applications table on this page lists the confirmed rows — check trim level and build year against your own fleet before ordering, because one reference can cover several body variants.

Three checks: the code printed on your old part must read 35399-2S133; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

A supersession happens when the maker revises a injector service kit and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 35399-2S133 we list the current reference; ask our desk for written confirmation before a large order.

Aftermarket injector service kit comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.
