Intake Manifold for 2011–2019 Ford F250 F350 F450 F550 6.7L Powerstroke | SPELAB
Lee Mullert
2014 F350

This is a really nice set up inexpensive but well-made. Make sure you use 1/4 inch drive and torque wrench, if you get the half socket 10mm and multi size extensions even better it’ll make getting those two back bolts easy

Great Fit and Easy Install

Installed this SPELAB EGR Throttle Valve Delete on my 6.7 Cummins and the fitment was perfect. The kit was well made, installation was straightforward, and all the necessary parts were included. Everything lined up as it should and the truck runs great. Highly recommend for anyone looking for a quality replacement component.

Budget friendly

I originally had the Banks Monster Ram intake with grid heater delete, and costed $1200. Recently I decided to give Spelab a try for their 3.5” pusher style intake with grid heater delete. Fraction of the price and performs the same. Only regret I have was my purchase of Banks.

Cast aluminum cover

I am very happy with my unpainted cast aluminum cover. I didn’t have any issues with fitment or hardware / sight glass installation. It looks great inside and out. I wish I would’ve taken a picture before reinstalling the spare tire.

A fuel rail kit is a performance upgrade that replaces the factory fuel rail and lines with high‑flow components. It ensures consistent fuel pressure to each injector, supports higher horsepower builds, and often includes AN fittings for leak‑free connections. On LS engines, it's a foundational mod for forced induction or high‑RPM applications.

By itself, a fuel rail kit may not add significant horsepower. Its primary role is to support increased fuel flow required by larger injectors, turbochargers, or superchargers. It prevents fuel starvation at high RPM and ensures even distribution to all cylinders, which is critical for reliable power gains.

Yes. Quality fuel rail kits are designed to bolt onto the factory intake manifold and accept stock injectors and pressure regulators. They provide a direct upgrade path—you can install the rail kit now and later upgrade injectors and regulator without changing the rails again.

SPELAB fuel rail kits are typically CNC‑machined from 6061‑T6 billet aluminum, offering superior strength and heat dissipation compared to cast factory rails. The included AN fittings are usually made of 6061 aluminum or stainless steel with Viton O‑rings for high‑pressure sealing.

Not typically. Since the rail kit itself doesn't change fuel delivery characteristics, the factory ECU will adapt without issue. However, if you're also installing larger injectors or changing fuel pressure, a tune is required to adjust the injector pulse width and fuel trims.

Absolutely. In fact, fuel rail kits are highly recommended for turbo or supercharged LS builds. They provide the robust plumbing needed to handle increased fuel demands and higher base pressure (with an aftermarket regulator) that forced induction setups require.
