The Challenge: Making Small Turbos Work Harder
When Toyota designed the 3.4L twin-turbo V6 for the Tundra, they prioritized fuel economy and emissions over outright performance. The result? Small-frame turbos that work overtime and an intake system that chokes them out when you need power most. We saw an opportunity to fix both problems with one engineered solution.
Our Approach: Volume + Flow = Power
The SXTH CPLT Intake System wasn't designed by committee or thrown together from off-the-shelf parts. We took a systematic approach to solving the Tundra's intake restrictions:
The Science Behind the Gains:
- Increased Pre-Compressor Volume: More air sitting ready before the turbo compressor wheels
- Eliminated Restrictions: Smooth XLPE surfaces and optimized tube geometry
- High Flow & Dry Flow Cone Air filters: More airflow with bigger filters
- Direct Turbo Connection: No compromises, no adapters, just flow
Think of it like this: the factory system is like trying to drink a thick milkshake through a coffee stirrer. Our system gives those turbos the straw they deserve.
Real Numbers from Real Testing
We put our money where our mouth is with comprehensive dyno testing. Multiple pulls, consistent results, and even our "worst" hot test run beats the stock setup.
Also bear in mind these overall numbers for the truck are not true to whp/crank hp comparison. We had to use 4th gear which skews the totals in that regard.
What we need to pay attention here is the DELTA, the before and after of running the OEM intake, then the SXTH intake in the same conditions to present the difference in power between intakes.
Dyno Results: Conservative Numbers Tell the Real Story
We ran multiple pulls (3 OEM and 3 SXTH) to get the full picture, and here's what we found:
Best-Case Performance:
- +25.5 HP peak power (318.0 HP vs 292.5 HP stock) - that's 8.7% more power
- +20.4 lb-ft peak torque (335.2 vs 314.7 lb-ft stock)
-
Torque peak shifted 1,150 RPM lower (3,590 vs 4,740 RPM) for sharper throttle response
Even Our "Worst" Run retained power:
- +9.6 HP peak power (302.1 HP vs 292.5 HP stock)
- +5.7 lb-ft peak torque (320.4 vs 314.7 lb-ft stock)
- +20-29 HP gains in the upper RPM range where factory power drops off
Where It Matters Most: From 2,500-6,000 RPM, every single SXTH pull sits firmly above the stock curve. We're talking consistent 15-30 HP improvements throughout your actual driving range.
The Tundra Testing Challenge: Anyone who's dyno'd a Tundra knows about the infamous kickdown behavior between 3,000-4,000 RPM. The transmission gets confused and won't hold gear when ging wide open throttle below 4000rpm, forcing us to roll into throttle gradually. This makes us a little skeptical of results because the dyno operator's foot can't always be exactly the same between runs, up until 4000rpm where the throttle pedal is completely on the floor. So we stand by any recorded data above 4000rpm to redline where the pedal is 100% wide open.
Engineering That Works in the Real World
XLPE Rotational Molding Technology
We invested in XLPE rotational molding—the same process used for high-end fuel tanks. The result? Smooth tubes with smooth interior surfaces that won't crack, fade, or develop hotspots.
QuickSnap Magnetic Maintenance System
Here's where we got a little obsessive. Tired of dropping screws into your engine bay during filter changes? Our neodymium magnetic lid system snaps open and closed without tools. No more stripped threads, no more lost hardware, no more cursing in your driveway.
Integrated Design Philosophy
Most companies sell you a cold air intake, then try to upsell you $200+ turbo inlet pipes separately. We engineered everything as one cohesive system from day one. Better performance, better value, less hassle.
Why This Works: The Turbo Science
The factory turbos on your Tundra are working harder than they should. By increasing the volume of air available before the compressor wheels, we're essentially giving them a head start. This translates to:
- Lower wastegate duty cycles (less work for the same boost)
- Improved turbo response (faster spool, better throttle tip-in)
- Reduced heat buildup (happier turbos last longer)
- Enhanced turbo sounds (because let's be honest, this matters)
What's Next: OTT Tuning Partnership
These dyno numbers represent just the beginning. We're working with OTT Tuning to develop custom calibrations that fully exploit our intake's capabilities. Early testing suggests we're leaving power on the table with the conservative factory tune—stay tuned for those results.
The Bottom Line
We built the SXTH CPLT system because we got tired of compromise. Tired of intake systems that look good but don't deliver. Tired of buying multiple parts to get one job done right.
The result? A proven 14+ HP gain with improved throttle response, better turbo sounds, and the satisfaction of knowing you've got the best-engineered intake system available for your Tundra.
Your truck deserves better than factory restrictions. We built the solution.
