hi does anybody know what o2 sensor I should be putting in my car which is a 1997 MY 4.6 with a zavoli lpg system fitted I have found the correct one on island 4x4 but they say not for use on vehicles with LPG I emailed them for advice about which I should use but all I got was no can't help you any help as always is greatly appreciated

They just say that to protect themselves against warranty claims. It states it on most parts for fueling etc.

Thanks for that so I'll go ahead and get them then much appreciated
