Picit azért meglepődtem, viszont alapvetően a fócuszal szoktak példálózni, mármint ha problémás gázbeszerelésről van szó. Nem vletlen asse, hogy az angol gyári lpgs focusok erősebb (titán) szelepeket kapnak.

"Ford engine research revealed that petrol engines running on LPG require hardened valve seats to avoid premature wear, with an accompanying loss of performance and increased emissions. All Ford LPG vehicles incorporate hardened valve seats. Similarly, Ford spent $250,000 developing a new, twin-injector inlet manifold to provide optimum fuel delivery for each Bi-fuel engine. The spark plugs are unique to the LPG engines, as are the ignition coils on Transit, which offer a 25 per cent increase in spark energy. Regular maintenance has not been overlooked either, as Ford LPG vehicles have a plug-in diagnostic facility that allows qualified dealer technicians to quickly and accurately highlight any potential problem.
