No effect on engine... Actually engine perform much better on LPG. Japan is 2nd biggest auto LPG user country... they use to control emission..... Korea is biggest auto LPG user in world....

just wondering there should be a reason why lpg kit exists...[/QUOTE]
REASON 1. Your Govt/OGRA want to crook....they just want public money get wasted. they tried to sell LPG idea to replace whole CNG, they failed, then they tried to sell LNG kits idea they failed... now they will sell you high priced LNG in same sui gas pipe lines.
Reason 2. High pressure valve in CNG kit is the only difference in both kits. confirm it from some qualified engineer who has hands on experience. High pressure valve is slightly expensive. 2nd difference is cylinder....
Tesla islamabad is selling local made LPG cylinder... that aint imported either..... game of OGRA and some xxxxx
