Hi,
I have a Maruti Zen VX, 1999 model. I wish to know how can I improve upon its fuel effeciency and also add a bit of punch to the engine.

how much fuel consumption figure do u get now..
still to be on the safe side ,you can follow the following:

drive between 45-55kph .
keep your tires properly inflated.check them every week.

even though maruti says 20k for the spark plugs,change them at 10k kms.
change your engine oil every 5kkms.

dont ride your clutch.

get a k&n filter.go for the stock replacement filter.it will fit directly without you requiring to do any mods.

there are a lot of things that you can do like porting,an exhaust job and many more ,but then that depends on your wallet.

but i suggest for your daily use,a k&n will be enough.
for information on mods you can contact our resident car-doctor Dr.Dom.

hey, i read an OD article( in the "zen special" issue) that said you can fit a free-flow exahsut and tune it such that you can have better fe and very slight improvement in performance. correct me if im wrong.

yeah you are right
,many of us do have a free flow exhaust in our zens.
a free flow exhaust helps in the proper flow of exhaust gases and thus you do gain .
if driven normally ,ur FE does improve.

the free flow exhaust normally consists of the headers which are of tuned length which replace the exhaust manifold,then the expansion chamber and then the muffler.there is alot of debate on whether the cat con should be there or not.

you can go for a 4x1 exhaust and also a 4x2x1 .

the 4x1 helps in top end power delivery and so ur city driving will suffer.
the 4x2x1 helps in the lower end and mid -range .also the torque figures go up.
