Using this Injen Evolution Intake System is easy. First, make sure your engine is cool. Then, carefully remove the old intake system following the vehicle's manual. Next, install the new intake tube, using the custom CNC - Machined mounting flange to secure it to the turbo just like the stock attachment. Make sure it's tightly attached. When it comes to maintenance, check the intake tube regularly for any signs of damage or debris. Clean it gently with a mild cleaner if necessary. And remember, don't drive with a loose intake as it can affect performance and may even cause damage to your engine.
