Perrin BIG MAF Intake Kit – Subaru WRX STi


The Perrin BIG MAF intake is discontinued. If you need a high quality intake for your high power Subaru we highly recommend using the Cobb SF intake or Cobb redline Carbon Fiber intakes. If you are worried about maxing out the MAF sensor we also offer Etune services for SD and SD hybrid maps that will get your car running right without the need for a BIG maf housing. (This is a much better way of tuning a high power Subaru and will result in a smoother driving car and more reliable power than using a BIG maf housing.)
