If I want to add new ngk iridium plug,do i need to change plug wire too?...and also ignition coil too?Will original one in my esteem will
?I M having 1995 esteem with LPG gas kit & stock replacement K & N filter.

Hi,

The Iridium plugs are mainly performance oriented. To get the best out of them it is recommended to change to better quality plug wires and a ignition coil. I would not recommend the Iridium plugs in your application.

Hi,

I dont because I am assuming the vehicle is not going to be performance oriented considering it has LPG fitted. To do justice to the plugs he should change the plug wires as a bare minimum upgrade total cost of plugs + wires approx 5500-6000. Now decide is it justified.

Its best he specifies his application and usage.

Thanx
Enjoy Revving...

Hi,

If it is performance you are looking for then I would suggest you swap your filter with a conical one and put a good intake pipe. This will make more difference than the plugs & wires.

Isint a Conical Filter same as a performance filter?

Hi,

Yes means both. There are several good brands like MSD, Mallory, Spitfire, Magnacore, Accel etc. Good plug wires will cost from 3.5k for a set to almost 10k depending on the brand & model. Ignition coils will cost from 3k for the cylindrical ones to around 8k again depending on make, model.

Hi all,

When I decided to add K&N filter on my LPG run carburator esteem....same thing happenbed...even the dealer was not knowing whether this filter with LPG will perform or not........................& to my surprise it indeed....its performing so well.....my FE increased by minimum 1.5Km in daily mumbai traffic & travelling of 60Km daily.I think irrespective of LPG or petrol...this filter works & if driving condition remaining the same then definitly giveds good FE.
Hence I decided to go for iridium plug.I think what this plug do is to give more intense spark at less consumed voltage.Now in case of LPG...its being electrically resistive gas,normal plug has to work hard to ignite this fuel.If spark ignition intensity is improved then it results in better combustion & hence better FE.

I will post after running my car for a week.

Without K & N stock replacement filter my car returned 450Km per full tank of 45Kg in normal city driving.Now returning 500 with much omproved acceleration & improved torque ar entire range of rpm.

What changes in FE & power can one expect
