yes i m also using cng, and there is a major difference in the pick n smoothness of the car, tonight i chkd the pick more and amazingly it reaches 90 km in 2nd gear ! i was amazed that this is become my civic as my Exi goes over 100 in 2nd gear but this is alto
touched 150 easily will try more tomorrow. please note no headers done yet.
ppl were saying iridium plugs will give trouble in cng cars but so far these are not gvng problems , my one friend installed platinium tip autolite plugs , there is no differenc ebetween both in performance, price is much less of the autolite , i think 1000 Rs and iriddium are 2100 ! so the choice is yours.
