What does the fitting kit include ?

The fitting kit includes the pieces needed to assemble your part (screws, clamps etc..).

Duration of life/regeneration of a DPF or a catalytic converter ?

The regular cleaning of the DPF is mandatory. It consists in increasing the revolutions of the motor to more than 3000 towers on many kilometers. This causes an increase in the temperature of the motor and allows to burn the fine particles, so a regeneration of the DPF. When intervention is required at the DPF level, a specific light turns on on the dashboard. The vehicle loses power and goes into degraded mode. All interventions have to be carried out by a professional and requires a resetting of the parameters with the diagnostic case.

When the catalytic converter is damaged, it becomes noisy and makes a noise saying "of old pan".

The change of a DPF or a catalytic converter varies according to the manufacturers recommendations, between 80 000 and 120 000 km.

Technical Questions

INOX 409: Magnetized ? Manual welding ?

Our DPF and catalytic converters are 95% made of INOX 409 (bodies and pipes). The INOX is a stainless steel and therefore resistant to corrosion, thanks to the chrome present in its composition. For technical and mechanical reasons, the extremities of our products that serve as a junction between the different parts are, as for them, manufactured in steel S235.
The INOX 409 of the ferritic steel family reacts to magnets, contrary to received ideas, there is no correlation between magnetism and material quality.

For more precision, all our welds are hand-made.

Cordierite or silicium ? Are the products RELIABLE ?

Our DPF and catalytic converters are not made of cordierite or silicium carbide but of high quality ceramic.
Krosfou, above all is the BEST QUALITY on the market in 2022.
Just-in-time production ensures higher quality than dealers who often distribute the products stocked by their car brands/manufacturers on the date of release of the vehicles. Our products are all manufactured in technology 2022 !

The diesel particulate filters (DPF) and catalytic converters Krosfou do not rust: they are made of stainless steel (INOX 409) !
Equipped with high-quality monoliths, whose cells (honeycomb structure) have been treated with a "unique coating technology for the deposition of thin layers of rare metals", Krosfou DPF eliminate dangerous nanoparticles, (extremely dangerous, especially for children) and have exceptional longevity: they regenerate almost 100% when you drive a few tens of km on highways and expressways !

My product has a DIFFERENT LOOK from the original

No need to worry, your product mounts exactly the same way upstream and downstream of the part, by direct assembly.

This case of figure, although rather rare, can in fact present when the product hasn't been realized initially at the request of a car manufacturer (to supply one of its assembly chains on a specific model of vehicle). Our factory in Poland reserves the right to adopt the form that it finds most pertinent, notably in view of the permanent technological advances that It realizes. The principal subject being to put these at the disposal of the user in the best conditions.

Difference between catalytic converter and DPF: diagnostic case required ?

Catalytic converter: its principal function is to reduce the pollution produced by the exhaust gases. It transforms the most toxic constituents of exhaust gases (carbon monoxide, nitrogen oxide and unburned hydrocarbons) in less toxic elements (water, carbon dioxide and nitrogen). This transformation is possible thanks to a high temperature, reached after many minutes of driving.
The catalytic converter does not require the use of a diagnostic case.

Diesel Particulate filter: It is located after the catalytic converter, downstream of the exhaust line. The DPF retains, on its porous walls, solid particles that are generated by the motor. The DPF are mandatory installed in DIESEL cars since 2011.
The diagnostic case is required and only a professional can make the change of the DPF.

Do I need to reinstall the original heat shield ?

No, with the technology Krosfou 2022, the heat shields of the original parts are not necessary anymore.

Where are the products manufactured ?

Krosfou SAS is the official distributor for Southern Europe and the world of the first manufacturer of diesel particulate filters (DPF) and catalytic converters auto new high performance in stainless steel INOX. The products are manufactured in Poland.

More info HERE: Original NEW parts.

Can you manufacture DPF or catalytic converter on demand ?

Under reserve of a validation of your request by our factory.
