im thinkin of puttin a k&n panel filter in my standard airbox in my 1ltr. will it make much difference to the performance and fuel economy? im mainly afta more torque in 4th gear for overtakin- any other suggestions????????
i went for the cheap option and drilled my airbox :twisted: which gave the sound i was after and it felt a bit quicker in the colder months but come the summer with the hotter air etc. the car was definately slower and overall i used much more petrol - i've since coved the holes in my airbox with cardboard (stuck on with glue) Don't know how an air filter would affect things though :shock:
