VTT B58/S58 Head Port Block-Off / Built Check Valve Kit
The VTT B58/S58 Head Port Block-Off / Check Valve Kit is designed to either seal off or convert the factory head ports used by the OEM low-side PCV system. These ports in the cylinder head utilize engine vacuum to evacuate crankcase gases — but in the process, can allow oil to enter the intake manifold, leading to valve carbon buildup and other performance issues over time.
This kit provides two configuration options:
-
Block-Off Version – Completely seals the factory head ports to prevent oil intrusion and unwanted vacuum leaks.
-
Billet Check Valve Version – Converts the head ports into a robust internal PCV system using precision-engineered check valves. These one-way valves allow vacuum to function as intended while blocking boost pressure from entering the crankcase or charge tract.
By bypassing the factory PCV valve in the valve cover, the VTT kit replaces it with an improved three-valve internal system integrated directly into the cylinder head. This design improves reliability, simplifies plumbing, and ensures consistent crankcase pressure management — critical for both stock and high-performance B58/S58 applications. This kit does NOT require any tapping, meaning no metal to get into the engine etc. You simply tap the plugs or check valves into place.
Key Features
-
Eliminates oil draw-through into the intake manifold
-
Prevents carbon buildup on intake valves
-
Converts to an internal, head-integrated PCV system
-
Utilizes precision-machined check valves for boost sealing
-
Fully reversible — Block-offs or valves can be removed if needed
- No tapping is required. Easy install, by tapping the blocks or valve into place.

Looking to up your boost limit on just about any BMW vehicle that runs a 3 or 4-wire BMW map sensor including but not limited to S58, B58, N54, N55, S55, S63, B48, B47, B42, B57, B46? We were too, so we decided to make a very easy plug-and-play kit for 3, and 4-wire BMW map sensors. These kits will allow you to completely replace the 3-wire sensor with one of our sensors, leave your stock 4-wire in place for IAT sensing, and move the power, ground, and sensor signal from the factory sensor to our sensor. These sensors have the proper scaling which will allow your tuner to simply change your map sensor scaling in the tune, and the factory ECU will be able to utilize the sensor voltage with no problem. We are offering these in 5 bar (58 psi), and 6 bar (72 psi), and each comes with a plug-and-play harness, and optional fittings for ease of installation.
Note: For the S58/B58 our Factory style Pre-Throttle map sensor is also 5 bar, and will work fine coupled with the post throttle kit, but the scaling is different, if you want matching Voltages Pre/Post throttle you can run two of these.
A variety of install pics can be found below and - Here
Scaling PDF Links: 5-Bar / 6-Bar
Features include:- Plug and Play harnesses with no wire splicing
- Output wire for connecting a PI or external controller to your post-throttle map sensor for the most stable signal that is not affected by throttle closure
- Different fittings are available for your plumbing needs.
- Can have matching voltage signals for pre/post throttle for ease of tuning, and boost reference
- B58/S58 etc Pre Throttle - 3 Wire Harness (Charge pipe to 1/8" NPT adapter needed, for B58/S58 90 degree adapter needed to provide sensor clearance)

VTT noticed a hole in the VTT A9X Supra/BMW Z4 / G2X / G42 Billet Diff Lock Down Kit market for a high-quality, lightweight, NVH-friendly, and easy-to-install Diff Lock Down kit to improve diff stability under launching, and hard cornering. So we did something about it and went to work on a very innovative design that 100% positively locks the diff down from movement, while shielding it from adding a ton of NVH, and can be used with the stock diff, and subframe bushings. This design uses existing mounting points on the vehicle, you do NOT have to remove the subframe or the Diff to install. Simply remove 4 diff bolts, drill two holes in the subframe slightly bigger, install two M10 riv-nuts, and install the lockdown, you do not even have to move the exhaust. A typical install can be 15-30 minutes for someone who is experienced working on vehicles, an hour if you like taking it slow. You WILL need a Riv-nut tool to install the Riv-nuts, we provide a link below for what we recommend on Amazon. Features:
- Lightweight 1.5 lbs for the entire lockdown plate
- Uses FOUR connection points on the Diff, and two on the subframe for the ultimate in positive diff location, this will stop all diff movement on launch, saving your guibos, etc
- 100% Billet construction from 6061-T6 aluminum
- Anodized in 4 colors for corrosion resistance, a long-lasting finish, and good looks
- The subframe does NOT have to be removed for installation
- Uses all 12.9 grade hardware
- Does not add excessive NVH
- Positively locks down the diff to eliminate all unwanted movement under launches, acceleration, cornering, etc.
All products that are designed to stiffen or reduce drivetrain movement inherently have the tendency to increase NVH or Noise, Harness, or vibration. While these bushings inserts have been found to add little NVH in most instances. Your results and sensitivity to NVH may vary. This product is designed to reduce drivetrain movement, and that was the goal when designing and manufacturing this product. Returns for NVH are not accepted once products are installed.

VTT Modular Silicone/Billet Intake System – BMW G2/3/4X B58TU
VTT is proud to announce our Modular Silicone/Billet Intake System for the BMW G2/3/4X platforms equipped with the B58TU engine.
After extensive testing and countless hours of fitting, we’ve created an intake system that delivers both optimized airflow and factory-level fitment.
Why Upgrade?
The factory BMW airbox itself performs well, but the intake tract down to the turbo is full of twists, turns, bellows, and even a built-in silencer that restricts flow and robs power. Our system eliminates these bottlenecks and replaces them with a 3"–3.5" free-flowing silicone intake tube, paired with either:
-
The stock airbox (for OEM appearance and sound), or
-
Our 6" high-flow cone filter with integrated velocity stack (for maximum airflow and sound).
From testing, we’ve confirmed the stock airbox is capable of supporting up to 700WHP. Beyond that, we recommend stepping up to the 6" cone filter system.

-
The Factory B58 TU water neck is plastic and is right in the path of your charge pipe if you lose a connection and it blows off. If this does happen to you it can break the plastic neck emptying your coolant in seconds causing you in the best-case scenario to be stranded, and in the worst-case scenario expensive engine damage. Add some cheap insurance with our Billet Water neck.

VTT is proud to announce another product in our carbon fiber product line. The BMW F-Series B58 Modular Carbon fiber intakes system! We COMPLETELY do away with the entire factory intake tract, including the accordion hose, the turbo muffler, all of the restrictive bends. We then replaced it with a smooth radius 2.5"-4" Silicone intake pipe with wire impregnated to ensure strength and longevity. This is coupled with our billet intake connection for an OEM-like fit, and finish. We then created a 100% carbon factory-style intake top and coupled it with our high-flow cotton pre-oiled filters. These tops are 8 layers of 100% carbon, not a single layer wrapped over plastic and they are 1.3MM thick with our logo vacuum printed onto the tops, with a UV-resistant gloss clear coating. This is not only strong but will resist discoloration for an extended period of time. The filters themselves are made with a heat-resistant silicone base, a high-flowing cotton weave element with a pre-oiled design to catch contaminates but allow free flow. But we didn't stop there! For the crowd looking for increased intake sound, we also made this compatible with our 4" Cone filter for increased flow, and much louder intake sound! These are available for stock, AND aftermarket turbos. Filters are available by themselves for a flow upgrade while keeping the stock look here - https://vargasturbo.com/product/vtt-f-series-bmw-b58-high-performance-drop-in-air-filter-upgrade/ Features:
- Completly modular, can switch from Carbon top to Cone filter all using our silicone intake tube
- 50 States Emissions Legal (Carbon fiber top kit only. The Cone filter option is legal for racing use only in California. Always follow all local emissions rules)
- Easy to install 15-30 minutes even for a novice
- A Beautiful Carbon Fiber finish really adds class to the B58 engine bay
- Filters can be cleaned forever meaning never buy new filters
- Completely removes the restrictive stock intake pipe, NOT only the turbo muffler elbow
- Completely reversible if you ever want to remove
