Download For best performance and continued durability, please take note of the following key points: 1. Use only premium grade fuel 92 octane or higher (R+M/2). 2. The engine must have stock compression ratio. 3. If the engine has been modified in any way, check with Vortech prior to using this product. 4. Always listen for any sign of detonation (pinging) and discontinue hard use (no boost) until problem is resolved. 5. Perform an oil and filter change upon completion of this installation and prior to test driving your vehicle. Thereafter, always use a high grade SF rated engine oil or a high quality synthetic, and change the oil and filter every 3,000 miles or less. Never attempt to extend the oil change interval beyond 3,000 miles, regardless of oil manufacturer’s claims as potential damage to the supercharger may result. 6. Before beginning installation, replace all spark plugs that are older than 1 year or 10,000 miles with original heat range plugs as specified by the manufacturer and retard timing from factory specifications (follow the procedures indicated within the factory repair manual and/or as indicated on the factory underhood emissions tag). Do not use platinum spark plugs unless they are original equipment. Change spark plugs every at least 15,000 miles and spark plug wires at least every 50,000 miles.
