ACDelco GM Genuine Parts Fuel Injectors

ACDelco GM Genuine Parts fuel injectors are an electro-magnetic valve that meters fuel into the engine's intake manifold or cylinders for combustion, and is a GM-recommended replacement for your vehicle's original component. The engine management computer operates the injector by applying an electric current to the injector solenoid winding—this causes the needle valve to open, and allows the pressurized fuel to be atomized into the intake airstream. These original equipment fuel injectors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. They are also offered in kits with the necessary parts, such as seals, clamps, and spacer.

FAST LSXR Intake Manifolds

The engineers at FAST teamed up with the airflow specialists at RHS to develop a 3-piece, polymer intake manifold. They are constructed from a proprietary advanced polymer material that offers a host of benefits over aluminum aftermarket intakes, including lighter weight and improved strength and heat dissipating characteristics. While they feature a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm throttle body, they can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows for the use of factory accessories without modifications or clearance concerns. FAST LSXR intake manifolds' 3-piece modular design allows for easy disassembly and porting. This new design gives you the ability to remove individual runners from the manifold for modification.

BD Diesel Killer Grid Heater Upgrade Kits

BD Diesel Killer grid heater upgrade kits are purpose-built to address a major flaw in the 6.7L Cummins engine--the electrical connection to the intake grid heater. When powering the grid heater, 200 amps pass through a small bolt and nut inside the intake and over time is known to deteriorate and eventually arc and break off. The nut drops into the engine, leading to extensive damage to the piston, head, and valves. BD's Killer kits upgrade that flawed electrical circuit by eliminating the problematic bolt and nut inside the intake while retaining stock functionality of the heater. The kits are cost-effective and easy to install. Additional features: * Allows for full heat output with the stock intake grid heater * Fully emissions compliant * No modifications or tuning required * Self-locking threads built into the lower busbar prevent backing out and compromising electrical connection * Kit includes replacement hardware and gaskets, along with special tools required for the job
