dear pakwheelers aslamo aliekum i have a toyota belta car 1000cc and i have a problem that is i feel loss of power after some time . when the car is cold the pick and acceleration is great but as the engine heats up a little i.e after driving for 50 km the pick and acceleration both are zero , the car struggles to pick up , i got a tunning and the problem was still there
now after long research i came to a solution that was according to me the after the engine heats up a little 
hot air is sucked into the air box as this area is really hot so that could cause loss of power , here the option for me was to add a cold air intake but i wanted an alternate , so wat i decided was to add the air box of suzuki cultus
and after setting up suzuki cultus air box it would look like this
so i wanted to ask all the experts that will this be useful in any way , will there be any increas in power and is the location correct beacuse it is away from the exhaust area so it wont suck hot air , please suggest me what should i do should i keep its original air box and keep on driving it the way it is or cultus air box will be helpful
regards
