Using this intake horn is easy. Just replace your old intake horn with this 3.5' one, as it's compatible with the factory IHI Turbo or upgraded drop - in IHI Turbos and OEM or aftermarket intakes. There's no need for any tuning. When it comes to maintenance, keep an eye on the gasket and the stainless hardware. If you notice any signs of wear, replace them. Also, check the powder coating regularly. Since the product has an estimated lead time of 40+ business days, plan your purchase in advance.
