Yes they are overrated when you consider their application on stock cars. They wouldn't make any power difference. The stock plugs should suffice your needs. You will not notice any power gains practically but psychologically you might feel some power gains since you spend money on it

I had spoken with a guy who carryout mods. He told me not to go for iridium in 1.6 as only platinum is needed for 1.6.

Default 1.6

the 1580 cc engine produces 272+bhp in grande punto,
the cam timing of the 1596cc<palio> is restricting the power out put. the cam eventd @0 deg will produce least amount of performance... still the engine produces heaps of performance... check ther valveoverlaps of other performance engines n ull understand thee difference,,,,

AFAIK, the ONLY Fiat engine with 1580 cc of displacement was the one in the Tipo and Tempra in the '80s, which put out 83 bhp. The Grande Punto puts out a MAXIMUM of 130 bhp from a 1.9 JTD. Maybe you are referring to the rally-spec Super 2000 Punto Abarth, which puts out 280 bhp from a 2000cc mill, which is actually borrowed from the Alfa 156 WTCC car.

The highest specific output for any 1.6 litre engine is 200 bhp, on the old Nissan Pulsar/Sunny GTi-R.

Please stick to facts and figures, and make sure they are true. Otherwise I will be forced to bring in my 6 litre Hemi-powered Alto which gives me 38 kmpl.

Nope,the earlier Sienas/Weekenders based on the Palio Mark I sold in India had the 1580 CC 98 bhp engines from the 'Torque' family.These had the 16 bit ECUs.Its only in 2002 that we had the 1596 CC engines with 32 bit ECUs plonked in Palios.

But 272+ bhp coming from a 1.6 in a Grande Punto.Now where did that come from ? TURBOSAM, enlighten us Sir.For starters, the Grande Punto does'nt even have a 1.6 engine option in UK or anywhere else.Or is this the 'Super 1600' rally spec engine or somthing of that sort?
