Just want to have feedback on twin head bosch plugs:

1.Does it really improve fuel economy?Can I put them in Santro?
2. I have heard that they improve engine performance in cars with CNG.
3.Price of plugs?

Need your technical views on that.
Thanks and will appreciate your input.

the enercon guy(G-6) has always recommed me to get the two tip spark plugs instead of the four tips ones.....

i'm using 2 tips one in my CNG corolla XE,
and the 4 tips one in my civic

din feel much of a difference...

NGK Iradium IX spark plug made in japan cost about Rs 2700 (4 plugs) are the best. they increase the torque of car.

irridium plugs + wires + ignition coil + distributor,,,,,,,,,,and u will get some real change

As far as I know 2 or 4 tip plugs are of no use in smaller capacity engines.

Yes but they work great in medium or large capacity engines and specially in EFI engines.

About the price of these Bosch plugs ranges Rs. 1400-3000 thats for 4 plugs. (correct me if I am wrong).

hamdani_08 (hamdani_08) 2007-01-23 05:47:00 +0500 #13

about the price

the two tip ones are for 180 rs each

while the 4 tip ones are 225 rs each
