Product Description

  • Quality Big MAF cold-air intake for the 2015-2021 Subaru STI.
    • 73mm MAF diameter is good up to about 450awhp.
  • Fits with ETS and Mishimoto FMIC (and all TMIC).
    • NOT compatible with the Perrin FMIC (see other type-2P intakes).
    • Please email sales@kstech.biz with info about other FMIC applications.
  • High filter location eliminates typical-CAI worries about water ingestion.
    • Hydrophobic filter sock is available for extremely wet conditions - see related products below.
  • Custom Tuning is absolutely required with this (and any other) big MAF intake.
    • For a base map, multiply the stock MAF table by 1.23 and fine tune from there.
    • Once tuned, this intake idles and drives like stock.
    • Engine damage will happen if you drive your car under boost untuned with this intake.
  • Optional Heat Shield is recommended and lowers intake temperature by 10-20 degrees.
    • Heat Shield comes notched to clear intercooler piping when needed.
    • Powder coated semi-flat black.
    • Comes with mounting bracket when no Heat Shield is selected.
  • Powder coating of the intake tubing available.
    • NOTE - please allow 2-3 business days before shipping when selecting any coating.
    • For more details about coatings see related products below.
  • Reinforced silicone couplers.
    • 100% Stainless liner-type hose clamps do not cut into the coupler.
  • Made in the Reno/Tahoe area of Nevada, USA.
    • Precision CNC-machined MAF Flange.
    • Beautiful welds done by local craftsmen.
    • Smooth mandrel-bent tubing.
    • Accurate and clean waterjet cutting of heat shield and brackets.
  • AEM DryFlow oil-free filter is standard.  Very high-quality velocity-stack filter.
    • Replacement filter is AEM #21-203DK (see related products below)
    • Hydrophobic filter sock is AEM #1-4000 (see related products below)
