Winter air is dense, and your diesel engine is begging for more flow. If you've been eyeing a High-Performance Intake Manifold, SPELAB's Black Friday & Cyber Monday (BFCM) event is the moment to pull the trigger.
Why Prioritize the Intake Manifold This BFCM?
Whether you are shopping on Black Friday or waiting for Cyber Monday deals, the Intake Manifold (or Intake Horn) should be at the top of your wishlist.
🛠️ The Technical Edge: Why Upgrade?
Stock manifolds on the 6.7 Cummins and Duramax engines are restricted by emissions heaters and narrow casting designs. Upgrading to a SPELAB Aluminum Intake Manifold delivers:
- 40%+ More Airflow: Mandrel-bent tubing removes the choke points.
- Safety First: For Cummins owners, our intake horn eliminates the dreaded "Grid Heater Bolt" failure risk.
- Cold Weather Performance: Maximizes the benefit of winter's dense air density for lower EGTs.

The Strategy: Nov 21 vs. Nov 28 (When to Buy?)
This year's schedule is tricky. Here is our expert advice on how to time your purchase:
Option A: The "Safe Bet" (Buy Nov 21 - 27)
Use code BFCM15 for 15% OFF.
Why now? If you are buying popular items like the 6.7 Cummins 3.5'' Intake Manifold, stock might run low before Black Friday. Locking it in now guarantees you get the part for your holiday install project.
Option B: The "Sniper" (Buy Nov 28)
Use code CL20 for 20% OFF Selected Items.
The Risk: This code is valid starting Nov 28 (Black Friday) and is likely limited to the First 200 Orders. You need to have your cart built and ready to checkout at midnight. This is the deepest discount of the year.

The $800 Cart Formula (Intake + Delete)
An Intake Manifold alone (~$350) won't get you the big gift. Here is the "Pro" combination to hit the $800 tier:
- Intake Manifold: The foundation for airflow.
- EGR Delete Kit: Since you are removing the intake horn, it's the perfect time to perform a Full Delete to solve soot issues.
- CCV Reroute: Keep oil out of your new intake manifold.
Result: You get a complete engine overhaul, earn 3X Reward Points (Members Only), and get a free Exhaust Tip to finish the look.
Cyber Monday & Last Chance (Dec 2)
Missed the Black Friday rush? The BFCM15 code (15% OFF) is valid through Cyber Monday (Dec 2). This is your final chance to grab parts before prices reset for 2026.
