If you’re serious about squeezing every bit of power from your Honda Civic Type-R, then the PRL Motorsports High Volume Intake System Big Bore MAF housing upgrade is something you should definitely check out. This isn’t just any upgrade; it’s the largest MAF housing you’ll find on the market, designed to handle over 600 horsepower. That’s a hefty jump—about 47% more airflow than what you get with the stock MAF housing or the Standard Bore HVI MAF. Trust me, that kind of airflow makes a noticeable difference when you’re pushing your ride to its limits.

What’s really cool about this upgrade is how our engineers have fine-tuned the volute design and positioned the MAF sensor flange. This attention to detail helps keep your fuel trims rock-solid, so you won’t be dealing with any hiccups when you’re on the road or track. Just a heads-up, though: you’ll need to get a tune and MAF scaling to make the most of this big bore setup, and it's specifically designed to work with our High Volume Intake System. We’re talking to those of you who are aiming for that sweet spot of over 450 horsepower.

What’s in the kit?

• (1) Billet Aluminum MAF Housing—sturdy and ready for action
• (1) 4-Ply Silicone Hose—flexible yet tough
• (1) 304 Stainless Steel Worm Clamp—because durability matters
• (1) Injection Molded Evap Fitting—fits right in

Fitment:

• Honda Civic Type-R FK8 (2017-2021)

Important notes:

• This upgrade fits all variants, including RHD and international models.
• It’s compatible exclusively with our PRL Motorsports High Volume Intake System.
• Works with the factory turbocharger inlet pipe or the PRL Motorsports Titanium Inlet Pipe.
• No ECU calibration needed for the standard bore MAF housing, but you will need it for the big bore option.
• If you ever want to switch back, converting from the Big Bore MAF housing to the Standard Bore MAF housing is totally doable.

If you’re looking to take your Civic to the next level, this upgrade is worth considering. It’s built for performance and designed with the serious enthusiast in mind.
