To unleash the true potential of your 2.0T, the K04 turbo that is equipped on the Golf R / S3 is a much more robust choice than the factory equipped IHI (KO3) turbo, which runs out of breath mid-way in the RPM range. The HPA K04 Hybrid upgrade offers a higher operational boost range, while still working with the stock componentry; making for a natural and cost-effective upgrade. This K04 Hybrid conversion allows for a seamless integration, without the need for custom fabrications or aftermarket diverter valves. 

HPA has now developed our own high performance K04 Hybrid Turbo conversion that allows the factory K03 diverter valve to be installed in the OEM location, without a CNC port adapter. Our K04 Hybrid turbo assembly is one of the most advanced units available in North America, featuring many benefits over the competition.

With a market flooded with poor quality aftermarket clones and modified OEM assemblies, HPA has taken a fresh approach to supplying its customers with a K04 Hybrid Turbo for the Gen 1 and 2 EA 888 and EA 113 engines at an affordable price.

Reworked OEM parts result in high costs with no appreciative performance gains. For over two decades, HPA has been building hybrid turbines for the VR6 powertrain, working with the very best suppliers both overseas and domestically. HPA ensures the tightest quality standards are maintained in castings and the assembly of our proprietary CHRA's which feature a larger rotor and steeper turbine fins for increased tq delivery and rpm range.

HPA’s K04 Hybrid uses a newly cast compressor housing to incorporate the factory placement of the diverter valve. By casting the housings, costly CNC adapters and housing modifications are no longer required and associated costs and manufacturing time are removed from the kit assembly. To ensure a good result at first fire up, each HPA K04 Hybrid includes a new diverter valve representing the latest design updates from the factory.

Features:
  • Gain up to 355HP / 347TQ
  • Direct Replacement (in most cases)
  • Compact Design Allows for Faster Boost Response and Turbo Longevity
  • Turbo Muffler Delete for Smoother Exhaust Gas Flow
  • Simplified Design for Ease of Install
  • Diverter Valve in OEM Position
  • Block-off plate for PCV system (TSI)
  • Knife-edged, billet compressor wheel
  • Quicker Compressor Spool
  • Higher Output Across the Full RPM Range

K04 Bundle Options
As the factory IHI/KO3 runs out of breath at 5500rpm, the performance advantage of the K04 can be maximized by adding HPA’s Cast 2.0 Short Runner Intake Manifold. As the K04 pumps more air from 5500 RPM to redline, the HPA intake will support this demand by flowing 12-24% more air into each individual intake valves set. With the 2.0 Intake Manifold’s 42% larger intake plenum, initial throttle demand will be met with greater volume, allowing your software calibrator to develop more low end TQ. Take advantage of HPA’s race developed calibrations to fully maximize the RPM band of your 2.0T.

Good fit
Both filters fit well on my 2019 Honda CRV. I was able to replace without struggle. Did it on my own first time.

Good Fit for 2025 Honda CR-V EX-L
Very happy with purchase. Fit like a champ. Be prepared to work to change the engine air filter. It is more about Honda's design the the filter itself.

Very durable and quality produced.
These filters seem very durable and quality made. The air filter looks exactly and feels exactly the same on the factory filter and very easy to replace. The cabin filter was also very easy to replace. This cabin filter feels a lot heavier and higher quality than the factory OEM. Be sure the rigid sides of the filter will fit on the left and right side when installing. If you try to install the filter with the information written on it facing out, then the cover will not fit properly. When the filter is in place correctly, the cover will be easy to put back in place. Both filters seem very durable and quality made.

Perfect fit
I started changing my own filters about 10 years ago when I realized how much I could save, and how incredibly UNcomplicated it is. Anyone can find super easy instruction and videos on YouTube. Obviously some cars differ, but I've yet to find one that isn't as easy as replacing batteries in a remote. These filters are the exactly same size, and are made from good quality materials that are equally as good as the OEM filters I pulled out of my 2025 Honda CRV Gas vehicle. They're wrapped in plastic, so they're as clean as an be when you get them. It literally takes less than 10 minutes to switch out these filters, so you're saving a bundle by doing it yourself! Compared to having a dealer do it, this is a super great value, as they not only charge for labor, they probably charge twice as much for the filters themselves. So far, I have had any issues with air flow, and have not gotten any weird warning signs, so clearly they're functioning in the same way the dealers parts do. I mean, they look and act just like the parts already in the vehicle, so I don't expect any issues.

Easy DIY replacement
This engine and cabin air filter kit was an easy and worthwhile replacement for my vehicle. Both filters fit exactly as expected and matched the originals in size and shape. Installation was quick and straightforward. The cabin air filter slid right into place, and the engine air filter seated properly with no gaps or bending. Airflow immediately felt improved, and there were no warning lights or fitment issues after installation. The filters appear well made and sturdy, not flimsy or overly thin. It’s convenient having both the engine and cabin filters included in one kit instead of purchasing them separately, especially for routine maintenance. If you drive a compatible CR-V or Civic and want a simple, cost effective DIY replacement, this kit does the job well and saves time.
