The Miata High Flow Air Inlet Kit for the 1989-93 Miata combines the advantages of a low restriction K&N air filter with a smoother air passage into the factory air meter assembly to improve throttle response and horsepower. Designed and engineered by Racing Beat, this attractive assembly, with its polished aluminum casting, positions the air filter cone away from the exhaust header to minimize the intake of heated air. This Miata intake has proven extremely popular over the years with Miata owners worldwide. Legal for use in SCCA Production and STR classes.
As reviewed decades ago by Miata Magazine, "Around 3500 rpm a new pull develops that increases with the RPM. Around 5,000 the power gain is easily noticed over the factory system. The Racing Beat intake will look good under any hood with its curvy aluminum elbow, but under its good looks is a performer."
Years ago Sport Compact Car Magazine reviewed this intake in the "The Great Intake Shootout" in the July 2000 issue and stated the following: "This intake was the puzzler of the test. Despite its higher intake temperatures, it remains the power king of the temperature-corrected dyno tests. Due to that fact, it's our favorite. Its hard to argue with the most power, the best sound and the best price in one intake. Plus it takes minutes to install and looks pretty cool." To review this article, click here.
Our dyno tests have shown a 6 HP increase over the stock air filter assembly. This dyno test was conducted on a stock 1995 Miata (1.8 ltr.) upgraded with our High Flow Air Intake. To view a graph of the dyno test results, click here. (PDF)
Only minimal effort is required to complete the installation of this assembly and requires only the use of simple hand tools. Use of the K&N Recharge kit (available from our website) is an inexpensive way to clean, protect and prolong the life of your air filter.
Note: We are often asked if this air intake assembly is compatible with a specific aftermarket shock tower brace. For detailed information on the use of a shock tower brace on the Miata, visit our Shock Tower Brace Technical Information page. With the vast number of aftermarket braces available on the market, we are not certain of the compatibility of these units with our air intake. We suggest you contact the part manufacturer, dealer, club members, newsgroups, and on-line forums to determine the compatibility of various aftermarket part combinations.
