Product came in earlier than expected and is made out of high quality materials. SPELAB hasn't let me down yet!!
The product installed perfectly high-quality superior part. For my 2022 f350. Coolant reroute kit.
Everything works great all parts fit hangers fit have pictures if needed
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
Makes truck breathe better and will definitely blow your y bridge out so do that while you’re in there looks great and fits up pretty good not perfect
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.
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.
Great product
Good product fast sipping was not that bad of a job
Nicely done ✅
Easy installation and everything fit perfectly. The kit is well-made, comes with the necessary components, and worked as expected. Shipping was fast and the quality exceeded my expectations. Highly recommend for anyone looking for a reliable EGR delete kit.
Very impressed with the quality of the cooler. Couldn’t find any instructions for the install. However, I was able to figure it out and plan to post a video for anyone else who may need help with the install.
Installed this on my 2015 6.7 Powerstroke and everything fit perfectly. Quality parts, straightforward install, and noticeable improvement in engine temps and reliability. Would definitely recommend this kit to anyone doing an EGR delete.
Installed on a 2019 Ram cab and chassis with no issues. Fitment was good, quality looks solid, and throttle response feels better. Definitely recommend this intake horn/grid heater upgrade.
Its worked perfectly so far. Make sure to buy one that is the correct size and that there is room for it. The motor is larger then I expected but made it work and ive used it everytime I drive
FAQS
The 5.8L Windsor V8 shipped in 1997–2003 Ford F-150 (10th gen), plus 1997–1999 F-250. It also appeared in 1994–1995 F-150 with the Lightning package. Always confirm your VIN's 8th digit before ordering.
2V (two-valve) heads are factory on most F-150 5.8L engines and offer better low-end torque. 4V (four-valve) heads came on the 1996–2001 SVT Lightning and offer higher RPM power. Aftermarket headers are often head-specific—check before buying.
Long-tube headers remove catalytic converters and alter O2 sensor readings, which usually triggers a check engine light. A tuning module or hand-held tuner is recommended to recalibrate fuel trims and avoid running rich or lean.
Headers alone rarely improve MPG on a stock or daily-driven truck. The main gains are throttle response and exhaust flow at higher RPMs. Combined with a cold-air intake and a tune, modest mileage gains are possible.
Check the product listing for a CARB EO number. Most aftermarket long-tube headers are not smog-legal in California unless explicitly certified. Shorty headers with cats are more likely to be compliant.
Yes—always replace the header gaskets (and optionally the exhaust manifold-to-flange seals) when installing headers. Factory exhaust manifold gaskets are often partially reusable, but header gaskets should be fresh for a proper seal.
Header installation on a 5.8L Windsor is intermediate–advanced. It requires removing the steering shaft, unbolting steering components, and working in tight spaces. Budget 4–6 hours and use anti-seize on all bolts. A lift is highly recommended.
Most kits offer either cat-back (replaces rear section only) or header-back (full system). If running long-tube headers without cats, a full y-pipe to axle-back setup is typical. Match your desired sound level and emissions compliance.
On a 1997–2003 F-150, the factory warranty is long expired. If you have an extended warranty on a later-model truck with a swapped 5.8L, aftermarket headers may be flagged as modifications—check with your provider.
On a stock 5.8L Windsor (240–260 hp), expect 10–20 hp at the wheels from headers alone with a tune. Combined with intake and exhaust, gains of 25–40 hp are realistic. The stock 5.8L responds best to forced induction, not bolt-ons.
