I charged him Rs.5,000 which included the Rs.2,500 K&N Performance Air Filter and a longer vacume tube aswell.
The system is a bolt on, has it's Vacume tube mount and holds on to the stock carburator by two bolts. It takes 5 mins to remove or install it.
It takes an hour to make and if you go for a Air filter of your own or of a lower price range off my shelves the price will go lower..
