Why this product?

On this engine, the DPF is a well-known weak point: premature clogging on short or city trips, repeated forced regenerations, and the engine warning light coming on. A scenario many owners run into while searching for a solution on forums.

Exact fitment

Vehicles concerned (per the supplier listing, no detailed engine code): US Spec CR engines / CJAA. The supplier does not specify a detailed engine code for this product: check exact compatibility with your engine before ordering.

To plan for before installation

A suitable ECU tuning is essential to clear fault codes and avoid limp mode, not included in this kit.
