Hi,

I'm not much of a technical person so I shall try to answer this as best as I can. 4 point spark plugs, Iridium plugs, Platinum plugs all offer more positive and powerful sparks which in effect helps to combust the fuel more efficiently resulting in better starts etc.

"Bosch guarantees that you will feel improved performance in your vehicle when using a spark plug of the Bosch Platinum Series (Platinum+4, Platinum2, and Platinum, Super4). However, if you do not experience quicker starts, smoother acceleration, and improved fuel efficiency"(source Bosch faq)

I hope that helps.

Check out the above link as well. Should clear most queries.The thumb rule i sthe same for all performance brands. They all claim they are the best it is you the customer who has to decide.

Hi,

I assume you are referring to Bosch Super 4 for your Palio. I think they are available here for Rs1350/- set of 4.

Hey,

I'm shocked with that. Maybe the plug gaps were wrong. You do have to check them even if they are 4 pointers. Also you should replace your plug wires from OE to better quality ones to handle the extra voltage. I think you have had a lot of bad experiences with performance products. First the K&N conical filter and then the plugs.
