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.

FAQS

Yes, it is designed specifically for this engine, offering enhanced protection and heat resistance.

It improves cooling, reduces wear on components, and enhances durability under heavy loads.

Yes, it increases oil capacity, cooling, and durability, maintaining engine health in demanding conditions.

Many parts are DIY-friendly, but some mechanical knowledge is recommended for optimal performance.

The LB7 (2001-2004) is notorious for failed fuel injectors—the #8 injector seal is the most cited failure point, causing coolant loss and white smoke. The LLY (2004-2006) improved injector reliability but introduced EGR cooler cracking issues. Both generations benefit from head stud installations before any performance tuning, as factory head bolts can lift on modified engines under high boost.

Yes—if you're planning delete kits and a tune on any 2001–2016 Duramax, head studs are strongly recommended. The LLY head gasket and factory head bolts are the weak link under elevated combustion pressure from aggressive tuning. ARP head studs (part of the SPELAB Head Stud Kit) eliminate lift risk and are considered mandatory for any truck making over 500 HP or running E85.

SPELAB's All-in-One Kit for 2004–2005 LLY covers EGR, DPF, and CCV/PCV in one package at $306.99, rated 5.0 stars. This is the most cost-effective approach—single purchase, single install. Alternatively, start with the EGR delete + intake elbow to fix the most common failure mode (EGR cooler cracking), then add DPF delete later with a compatible tune from EFILive or H&S.

The factory CCV (Crankcase Ventilation) valve routes blow-by gases into the intake, causing oil buildup in the intercooler and intake elbow—a leading cause of the P0299/P0101 codes. The SPELAB CCV reroute kit redirects crankcase gases to the atmosphere or exhaust, eliminating oil coking in the intake system. Rated 4.63 stars from 30 reviews; a common upgrade before doing any other performance mods on the LB7/LLY.

Yes. Factory Duramax up-pipes use thin-wall tubing prone to cracking at the bellows, especially under high EGTs. A 2001–2016 LB7/LLY/LBZ/LMM up-pipe upgrade ($99.99 on SPELAB, rated 4.87 from 68 reviews) uses thicker stainless steel and thicker bellows for durability. On the LB7, the EBPV (exhaust backpressure valve) in the up-pipe is a common failure point—a bellowed upgrade kit eliminates it entirely.
