One off my sons runs a athena
25 pilot toomeys needle 360 main on his t5
Toomeys high flow foam on stock cage( flows the same as k&n holes in airbox
Runs perfect plug colour
But tranfers are way to low no bottom end
Took 40 thou off the bottom to bring the power on sooner which it did but the transfere then measured 109 degrees to ex 188
Ridiculous raising them up to 128/130 ish
Good transfere area good inlet size good tripple port ex
Hits really hard but only cause thre ain't no bottom or low mid no matter jetting or timing
