ramzsys : Thanks for the correction.. Its true this engine is known for longevity.. but as mentioned it is sluggish.. I was looking for performance air filters but so far had no luck. K&N say they dont have one for diesel ikon.
I am yet to check with pipercross and green.
mnhegde : The tyres are really good. I have tried taking the curves near krishnagiri and near thoppur with bridgestones but didn;t feel confident as I knew I was driving on the edge and any faster would get the tail out. With these i am able to take the corners above 80/90kmph...(This was done only once for testing.....)
