Replacing the stock delivery valves in your 12 Valve can substantially increase the low end power and fueling, in turn aiding in turbo spool up. Laser cut delivery valves are the most aggressive valve currently on the market, and Industrial Injection knows how to properly build them. These delivery valves have shown gains of 100HP over stock delivery valves, and flow 30cc's more than the 191's, and roughly 70-80cc's more than stock. These are a great delivery valve for trucks running nitrous oxide injection.
