Choose where you’d like to navigate to:


The unexpected product from a joint venture between Toyota and Subaru, The FR-S (Toyota) and the BRZ (Subaru) is an enthusiast’s dream come true. Both vehicles are light, agile, and affordable. Both are one of the most engaging even when compared with vehicles twice their price. The 2.0-liter flat 4 produces 200 horsepower and 151 lb-ft torque.

Due to a large part of the engine, the cars boasts an extremely low center of gravity that enhances handling. The 6-speed manual gets 22 mpg through the city and 30 mpg over the highway as the substantially more efficient 6-speed automatic, is able to get 25 mpg in the city and 34 mpg cruising on the highways.

Of the lot, the cars offer up decent performance allowing the driver to put their skill behind the wheel to the test. Both the BRZ and FR-S are built to excite the driving enthusiast who thinks driving is more than just mashing on the accelerator. Most car enthusiasts are looking for ways to increase horsepower in their vehicle and boost acceleration to have instant access to power.HOW


You can read our in-depth article on how an air intake works. This article covers many different aspects of air intake systems.

An aftermarket air intake is designed to replace your stock air intake system. The benefits in doing so are well worth the expense. Typically, aftermarket intakes are reasonably priced and requires minimal “know how” to handle installation on your own as opposed to other bolt-on modifications.

When choosing an aftermarket air intake, you’ll want to be sure to make the right choice for your vehicle. While most intakes produce the similar results, if you favor one result over the other, you’ll want to know what kind of intake is best for the outcome you’d like (such as horsepower, MPG, throttle response or acceleration).


That depends on a few different factors:

  • The price you’re willing to pay (generally $150-$400).
  • Sometimes performance gains are minimal at 5 or so horsepower gained but up to 40 horsepower.
  • If you have the knowledge and know-how to install one yourself as opposed to having it put on professionally.
  • Are you willing to alter the sound of your engine?

There are mixed reviews for intakes regarding the BRZ/FR-S as there are with any vehicle:

“Instructions were pretty good. I assembled the heat shield brackets and tubing while it was still out of the engine bay. Also put the intake tube through the heat shield while it was outside the car then put the heat shield into the engine bay. I was worried about dropping parts down under the engine. Love the intake, the pickup in acceleration, and that gorgeous noise when you cross 3500 rpm’s.”

As opposed to:

“Great sound on BRZ. Design has me wondering how much cold air is really being brought into the engine but between that and my full exhaust I am definitely seeing gains and MPG increases”.

In the end, be sure to do your due diligence on any intake you buy, prior to buying!

With that said, most aftermarket intakes have a great reputation due to their reasonable price, ease of installation and performance enhancements. Check out the chart below to help you with your aftermarket intake purchase.
