The 2.0L Hurricane 4 EVO is the heart of the 2024+ Jeep JL Wrangler 2.0T. While this engine delivers strong performance, many owners are finding the factory plastic diverter valves to be a weak point. If you are looking for the best Wrangler 2.0T BOV options, Turbosmart has released a game-changing solution: the Kompact EM VR34.
Unlike simple “BOV spacers” on the market that retain the factory valves, the Turbosmart Kompact EM is a complete OE replacement valve. It eliminates the factory plastic unit in favour of a precision CNC machined billet aluminium valve that requires no tune and is 100% plug-and-play.
WHY UPGRADE YOUR WRANGLER 2.0T DIVERTER VALVE?
The factory electronic diverter valve is prone to boost “bleeding” and can even crack under high heat and pressure cycles. The result is the kind of thing you actually feel from the driver’s seat: laggy throttle response, hesitation between shifts, and inconsistent boost when you’re working the engine, whether that’s towing, climbing grades, or anywhere else you need the turbo to do its job.
1. BOOST BALANCE TECHNOLOGY
The secret to Turbosmart’s reliability is their proprietary Boost Balance Technology. Traditional valves struggle to stay closed under high boost without using a heavy spring that slows down response.
With Boost Balance, the air pressure works with the valve, using the boost itself to help seal the piston. This ensures a leak-proof seal even under maximum load, resulting in sharper throttle response and elimination of “boost flutter” during towing.
Furthermore, no matter the upgrades you currently have or plan to make in the future, the Kompact EMs will support the higher boost levels and efficiently vent the increased charge air volume without the need to change spring rates.
2. PLUG-AND-PLAY (NO TUNE REQUIRED)
The Kompact EM plugs directly into the factory Jeep wiring harness. The engine’s computer (ECU) sees the valve as a factory component, meaning you get high-performance hardware without the risk of “Check Engine” lights or the need for expensive aftermarket tuning.
TWO WRANGLER 2.0T OPTIONS: DUAL PORT VS PLUMB BACK
Turbosmart offers two distinct configurations depending on whether you want a silent sleeper or an aggressive turbo sound.
THE LOUD OPTION: DUAL PORT (PART NO. TS-0223-1040)
If you want that iconic “Pssh” sound every time you lift off the throttle, the Dual Port is for you.
Audible vent-to-atmosphere (VTA) port. Staged valve body design to vent enough air for the sound while partially recirculating to satisfy OE engine parameters. The additional VTA port supports higher horsepower levels that come with modifications you may make to the vehicle.
THE SILENT OPTION: PLUMB BACK (PART NO. TS-0223-1240)
For the owner who wants the more robust construction alternative without the noise, the Plumb Back is the ultimate “sleeper” upgrade. It’s silent just like the factory valve, but it’s a direct, all-metal replacement for the fragile OE unit. You get all the boost-holding benefits of the Dual Port while keeping the cabin quiet.
RUNNING A 2018-2023 JL WRANGLER?
The pre-2024 JL Wrangler runs the older GME T4 2.0T engine. Turbosmart has that platform covered with the same Kompact EM lineup: the Dual Port (TS-0223-1086) and the Plumb Back (TS-0223-1286).
MAXIMUM BOOST, ZERO COMPROMISE
Upgrading your Jeep JL Wrangler BOV is one of the smartest “supporting mods” you can do for the 2.0T engine. By replacing the plastic factory component with Turbosmart’s billet aluminium Kompact EM, you’re investing in the long-term health and responsiveness of your turbo system.
