As we've been developing products for both 2nd Gen TLX platforms, our team has received a bunch of inquires asking if/when we will have a High Volume Intake System for these vehicles. We wanted to explain our methodology regarding intake system development and explain why we will not be offering a HVI for either of these platforms.

One of the first steps in our product development process is determining the specifics and geometry of existing components in an effort to understand how/why things work. To do so, we disassembled the factory 11th Gen Honda Civic 1.5L Turbocharger to collect measurements and data. Fortunately for us, our team had a factory 10th Gen Civic 1.5L (Si) Turbocharger here to use for a side-by-side comparison. It is important to note that all 1.5L Turbo models for the 11th Gen Civic now use the same turbocharger part number. For those that may have missed it, checkout our Part 1 Blog Post!

Using aluminum investment casting instead of CNC machining will allow us to integrate many of our design's complex features that once required multiple pieces and operations into many fewer components. In turn, this gives us the ability to keep costs down, while also being able to drastically increase production speeds once molds are complete. We will still be using some machining for intricate finishing, such as threads, O-rings and top/bottom end caps. Most importantly, this casting process will allow us to implement one of the most innovative and effective designs in the automotive market yet!

Our team is constantly thinking of ways to improve and add more flavor to the PRL Motorsports product line. Over the years we have received an overwhelming amount of inquiries regarding exhaust system development, but unfortunately were not able to take on this workload in the past. Now that our team has expanded and production has continued to streamline, we are able to begin looking into the manufacturing of exhaust systems, starting with the 11th Gen Civic platform. After scanning both the Si and Non-Si models' exhaust systems, our Product Development Team has started discussing some pretty neat concepts - we will be taking a look at the 2.0L exhaust system as well. Stay tuned for updates!

In past years we have specialized in inclusive turbocharger kits for a variety of reasons, mainly due to the fact small-frame turbochargers limit extreme peak-power goals for the ultimate record-hungry enthusiast. However, with more manufacturers normalizing low-revving, small displacement, direct-injection engines with integrated exhaust manifolds, these once feasible goals are becoming increasingly harder to reach. Instead, we will be using all of the data and experience we've learned over the years and shifting focus towards a drop-in upgrade in an effort to develop a turbo that appeals to the masses. Yes, we will be using our experiences with the P600 and other drop-ins as a starting point. Yes, we understand longevity and reliability is critical. Yes, developing a high-power capable turbocharger is still at heart - we are a performance company after all

This kit replaces the corrugated factory inlet hose with our better looking, smoother flowing 4-ply silicone hose. The pleats found in the factory hose disrupts air flow, which limits power potential and throttle response. This hose will be available by itself (with clamps and hardware as a kit), or available with our air filter as a full Stage 1 Intake System. Stay tuned for more updates to come!

This intake system for the 10th Gen Civic 2.0L will utilize the factory air duct to allow maximum airflow to the air box and filter. The High Volume air box will be constructed of rotomolded HDPE to help keep intake air temperatures low and for optimal fitment. We are currently looking into a new MAF housing and air box lid connection in an effort to streamline installation while still maintaining the the fuel trims, drivability and performance PRL Motorsports is known for. Stay tuned for updates!

We wanted to develop an intercooler upgrade that provides significant gains in terms of internal airflow volume and cooling without hindering turbocharger spool. After many weeks calculating a desired core size, optimal end tank fitment, all while avoiding CNC tooling constraints, we're finally able to order up a few custom cores for prototype sample testing.

Our kit will utilize a 3" OD cold side hard pipe with integrated methanol injection bung to replace the factory ~2.4" ID rubber hose to increase airflow and engine bay aesthetics. The kit will come standard with a factory diameter hot-side hose upgrade to maintain velocity and turbocharger spool. All supplied hoses are constructed of multi-ply high temperature silicone to increase durability and are "stepped" to promote smooth, laminar airflow. This kit also eliminates the factory charge pipe resonator, which increases audible turbocharger noise. Stay tuned for more updates!

Right off the bat, we can see that the 11th Gen is making considerably more peak horsepower. At peak horsepower, we are seeing a maximum difference of 19WHP and 20WTQ. This is due to Honda’s utilization of a twin scroll turbo (this term can be used loosely, we'll discuss this at a later date), dual port head, and the current generation having VTEC on the intake and exhaust side, which allows the head to flow much better at high rpm. This is also demonstrated by the horsepower and torque bump at peak boost, around 4200 RPM, whereas the 10th Gen torque curve begins to dramatically fall off as RPM increases.

We're ecstatic to see what the 11th Gen Civic platform is capable of. And yes, for those wondering all of our 11th Gen products such as the Resonator Delete Kit, Heritage Strut Bar, intercooler, charge pipe, downpipe, front pipe, Stage 1 Intake (silicone hose and panel filter) and flex fuel kit (once flex fuel tuning support is available for the Si) previously developed on our 2022 Civic EX 1.5T are also compatible with the Si Model. Stay tuned to see what else we come up with!
