Beware of cheap imported DPFs! We've
spoken to sellers in Asia who were
unaware that the ceramic honeycomb
substrate must have a catalytic coating
to work correctly (At high temperatures,
toxic gases such as nitrogen oxides and
carbon monoxide in the exhaust come
into contact with the catalysts and are
converted into harmless nitrogen and
water and less harmful carbon dioxide).
Incorrect size honeycomb substrates in
cheap imported DPF's will also increase
backpressure on the engine, causing
fuel economy and emissions problems.
