Using technically advanced spark plugs

Salam,
Yar it has been discussed many times that using two tip, four tip, or iridium plugs increases the performance of your car but the question is that HOW MUCH????
Will the performance gain be noticable or just a psycological effect.
And how much difference will the iridium plugs make as their cost is many times the cost of normal plugs.
I have heard that a set of three plugs costs Rs.3600. Does anyone knows the exact price and from where these plugs can be bought. Might be some shop in saddar as there is no shop in Chah Sultan which keeps these plugs.

If u use +4,+3,+2 plugs u get decreased mileage and no knocking, and about 1-2bhp increase. With platinum plugs you get longer plugs life i.e. no thinning spark as odometer rolls.

Iriduim plugs do not give u as significant fuel savings as +4,+3 or +2 give but it really raises you cars bhp rating

You can have a gooda set of four +4 plugs for 1000rs
