Review on Enhance Engine Performance with 🚀 K&N 63-2575 AirCharger Air Intake System by Andrew Jenkins

Not sure if anyone else has had this experience but I stumble at low speed or what could be due to the ECU hesitating on which gear to select after setting CAI. I will say it was a simple install that took a whole 30 minutes, of course I assembled a lot of packages (MAF, filer assembly etc) before removing the standard air intake which saved a lot of time. Do this if you want to simplify the task, executing this procedure seems slow. I'll disconnect the battery again and see if the ECU detects anything (worked when I installed the Mazdaspeed CAI on the Speed6 I previously owned.) Still not sure if it was worth it the noise is nice, but the stuttering between gears makes it annoying. Will update in about a month, it's been a week today and I don't see any difference in MPG.
