Unlock More Power: New COBB Tuning Upgrades for 2024+ Tacoma & 2025+ 4Runner

Toyota's next-generation trucks are here, and COBB Tuning just delivered the performance upgrades that 4th Gen Tacoma and 6th Gen 4Runner owners have been waiting for. Whether you're just starting your build or looking to optimize power delivery, shifting, and throttle response, COBB's latest Accessports and bolt-on upgrades offer real, measurable improvements right out of the box.

Backed by years of tuning experience and engineered for the all-new TNGA-F platform shared by both vehicles, these parts are designed to give you more control, more power, and a more connected driving experience without sacrificing any drivability or reliability.

Accessport V3: The Heart of the COBB Tuning Ecosystem

The foundation of any COBB upgrade starts with the Accessport V3 Tuner, available for both the 2024-2025 Tacoma 2.4L Turbo and the 2025 4Runner 2.4L Turbo. This handheld ECU and TCU tuner is your gateway to unlocking Toyota's conservative factory calibrations and replacing them with performance-minded tuning that makes your truck or SUV feel sharper, quicker, and more responsive from the driver’s seat.

With support for both engine and transmission tuning, the Accessport V3 allows you to:

• Adjust throttle response and torque delivery
• Raise or modify shift points and firmness
• Monitor up to six live engine parameters in real time
• Store and switch between multiple tuning maps
• Read and clear diagnostic trouble codes (DTCs)

Best of all, it comes pre-loaded with COBB’s Off The Shelf (OTS) maps, which are carefully developed to deliver instant results—no custom dyno session required. And if you're planning a full build, the Accessport supports custom tuning via COBB’s Accesstuner software, giving you room to grow as your mods get more serious.

Each kit includes a Gateway Bypass Harness to ensure full communication with your truck’s ECU and TCM, even in cases where Toyota’s factory safeguards would normally block flashing.

Stage 1 Power Package: Intake + Tune for a Smarter First Upgrade

For owners looking to go a step further, COBB offers Stage 1 Power Packages that bundle the Accessport V3 with a high-performance drop-in COBB High Flow Air Filter. This pairing is ideal for daily drivers, off-roaders, or weekend warriors who want better airflow and cleaner power delivery—without committing to major engine mods.

The air filter itself is built from proprietary synthetic nanofiber media that improves airflow while maintaining excellent filtration. It drops right into the stock air box with zero modifications, and it’s washable and reusable, making it a smart long-term upgrade. When paired with COBB’s OTS tunes, this filter helps boost response, especially in the low and midrange, where turbo lag and factory throttle settings often leave performance on the table.

These kits also include full support for transmission tuning, giving you the ability to adjust how your 8-speed automatic behaves under load, on hills, or during towing.

High-Clearance Turn Down Exhaust for Tacoma

If you’ve been off-roading your 4th Gen Tacoma, you already know the stock rear exhaust tip is a liability. COBB’s High-Clearance Exhaust Turn Down is designed to solve that problem by eliminating the bulky factory tip and replacing it with a tight, slash-cut turn down that tucks up and out of the way.

Made from mandrel-bent 3” 304L stainless steel, this exhaust mod doesn't change your truck’s sound or increase volume—it simply improves trail clearance, sheds a bit of unnecessary weight, and avoids getting caught on rocks, ruts, or steep inclines.

It reuses the factory gasket and hardware, and bolts on in minutes using the factory hanger. It’s an ideal upgrade for anyone running trails, crawling, or building a more functional overland setup.

COBB High Flow Air Filter: Easy Gains with Long-Term Value

Available separately or in the Stage 1 kits, the COBB High Flow Air Filter is a direct replacement for the factory filter in both the 2024-2025 Tacoma and 2025 4Runner. It offers better throttle response, improved airflow, and long-term reusability—all without requiring a tune.

That said, it pairs perfectly with the Accessport OTS maps, making it a low-effort upgrade that integrates seamlessly with your overall performance setup. It’s a great way to start modding your truck or SUV while setting the stage for future upgrades down the line.

Why These Mods Matter for the New TNGA-F Platform

Both the 4th Gen Tacoma and 6th Gen 4Runner are built on Toyota’s all-new TNGA-F body-on-frame architecture, which was designed for more power, better modularity, and improved rigidity. While the platform is capable, Toyota’s factory calibrations tend to play it safe when it comes to power delivery and shifting behavior—especially in the 2.4L turbocharged engine shared between both vehicles.

That’s exactly where COBB’s tuning solutions come in. Whether you’re chasing better drivability, prepping for future mods, or just want more excitement out of your daily drive, these upgrades offer immediate results with the flexibility to grow with your build.

From trail-friendly exhaust tweaks to full tuning and data monitoring via the Accessport, every COBB product is designed to integrate cleanly with the TNGA-F platform while giving you full control over how your Toyota performs.
