Diesel Particle filters  Changes to new car emissions legislation scheduled for 2009, the so-called 'Euro 5' standards, will make particulate filters as commonplace in diesel car exhausts as catalytic converters are on petrol cars. The goal is an 80% reduction in diesel particulate (soot) emissions but the technology's not without problems – We are regularly asked to force regeneration on  cars with the particulate filter warning light illuminated (indicates a partial blockage). It's clear that changes to driving style may be required too for maximum benefit from these systems. How do they work? Diesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust.

Stage 3 Ford focus kit, including hybrid turbo, intercooler, exhaust and injector
change to 440bhp.

The new M3 v8 programming protocols have just been released and together with the Milltek Exhaust system we hope to provide a complete conversion package for this engine. Up to 18  BHP is available with remap in the midrange with 40bhp on top  available from removing Cats and reprogramming to suit.
