The SLG Big Shot intake is a must when it comes to a big horsepower build. In most cases with motor builds, they demand more air that the factory intake just can’t provide. This is an excellent solution to that problem.  This has also been tested on factory machines and has proven to make horsepower in stock trim. The factory intake size is 1.75”, the SLG Big Shot is 2.5”. This also reduces the vacuum effect which will also keep a cleaner airbox. Keep in mind This is a DIY kit and does require someone with attention to detail for install. The kit comes with a template for where to cut your factory airbox. Once cut and fit up, drill a small hole through the airbox to screw in the provided fastener, this will hold the intake tube from sliding out. It is required by the end user to seal the gap between the air box and your new intake tube. I recommend U-418 urethane (not included, available on Amazon or your local windshield glass shop). You will also need to trim your hood to clear the stainless intake tube. We take no responsibility for any mistakes made during install as this is a cut to fit style install with many different ways of doing so. Be sure to plug or tape off your intake port after you remove your air filter until this install is complete. For any questions or tips give us a call.
