Spark Plugs in Baleno.. This thread I wanted to post yesterday and when today I was searching net just few minutes back saw a post from Samurai on this thread in google http://www.team-bhp.com/forum/techni...t-mileage.html
Well my Baleno is 2002 make and old timers know how much FE it gives me(I proved it to maruti people when they came to replace my Cam shaft sensor and that thread of mine is already exists in this very forum).Y'day I decided to change my spark plugs as I thought it is the time to change them though I had no probs what so ever in my car.I hence told my MUL Mass to provide me 4 nos.of original SGP Denso make plugs for replacement.While they were replacing them I was present and I saw that they were adjusting the gap in plug.Recommended gap is .7-.8 mm as per the service book given with the car(just open yours and check this) but before they plugin the plug into my car I asked them to give me my old plugs to see what gap they were having and to my very surprise I saw a narrow gap in all 4 plugs(old ones)and it was .4!!! I insist that I want the same gap in my all new plugs and not the one advised by MUL because I am getting super FE in my car.THey first told me sirji,use the gap advised by officials I told them no sirji I want .4 mm only.They agreed and put new plugs, I shall post results of this new change of plugs in next week as far as FE goes after having say 200-300 kms run with these new spark plugs with old gap.Right now car is running like before,no visible changes.Only one thing I did and that was I cleaned all cables connections- connecting to the caps and 2 boxes given above plugs as a routine.
Samurai I am repling to your post on 27th Dec.2005 here(check the link I posted above) I do feel that one should try this .4 mm gap and check the results for FE.btw my tyre pressure is ALWAYS 30psi recommened by MUL for my Baleno and I shift to 5th gear when my speedo shows 40-45 Kms/Hour.

Spark plug gap:-
The spark plug gap is set for various reasons. The larger the gap, the more time the spark spends in the combustion chamber and offers that much more time for the mixture to ignite. When the hi-tension voltage is low for some reason, then the temporary remedy is to reduce the gap so that the spark can jump the gap.
