If you're serious about boosting your Honda Civic Type-R's performance, the PRL Motorsports High Volume Intake System with the Big Bore MAF housing upgrade is definitely worth a look. This isn't just any upgrade; it's the largest MAF housing on the market, capable of handling over 600 horsepower. That’s a whopping 47% increase in airflow compared to the stock MAF housing. So, if you're pushing your Civic past 450 horsepower, this is what you need.

The engineers at PRL really nailed it with the design. They’ve fine-tuned the volute and positioned the MAF sensor flange just right, which helps keep those fuel trims super stable. Just a heads up, you’ll need to get a tune or MAF scaling after installation, and this upgrade is specifically designed to work with their High Volume Intake System. So, make sure you’ve got that in place before diving in.
