mazdaspeed cold air

I believe this cell RKEP0039 has been determined to be nothing.
Search the ECU tunning threads.
P0300 is random misfire. One of the causes is a leak on the intake.
Recheck and tighten the install.
Also, clean the MAF.

I have the MS CAI i had a similar problem. I capped the wrong vacuum line. Make SURE that you got the right one on the manifold. The directions are a little vague on that step.

underdrive pulleys require tuning? thats wrong too.
if you changed your crank pulley do the NVRAM Reset procedure that may help.
a CAI and underdrive pulleys wont set off a CEL requiring a tune in almost any car i could think of.

if you dont put the screen in you can get lean codes, had that happen after installing a motor, apparently when i took the CAI apart the screen turned sideways and wedged in the tube lol.
