I put two SLP Flowrites in mine. The only difference is that it would cough and choke when I punched the throttle. I ended up covering the holes back up. I would not put them in if I were you.

yea 2 of thoes seen a little over kill. id imagin ud have to play with the F/A miture runing that much of the intake open. i was thinkin maybe 2 or 3 maybe more of the litle like 1 inch one sith the foam filters on them. i bet if u ran with just one of urs uncovered ud see a little gain.
I was also told that you can just drill some 1" or so holes in the bottom of the box.

I bought the 1.5" D&D bullseyes,
Theres a dyno from DynoTechJim showing about 3HP gain with them and a better F/A ratio.
From his Archive page:
Sat/Sun 9/9 9/10 testing continues on Phazer, concentrating on airbox mods, big gains so far similar in percentage increase to F1000 Cat Y pipe. Posting will be done Sun/ Mon.
Thursday 9/14 reposted the Polaris IQ600 stock info with updates from Polaris engineering adressing the lean bog Rob experienced on his early release grass dragger. On the Yamaha front Brian Olson from Turbo Connection in Rapid City SD (makes turbo kits for Harleys, Triumph motorcycles (including the excellent turbo Tiger that I ride) and some snowmobiles including his girlfriend's Phazer.
Brian reminded me the the 07 PZ has deto sensors, an orange light comes on when the computer senses knock. So lean that baby out, but it still is smart to have A/F ratio info since we know that max HP is created at 12.5-13-1 A/F ratio"
Unfortunetly you have to pay to see the dynos but his report is very nicely done and was worth the $20 to me last year.

I also bought a sapre airbox cover to revert back to stock, cost me all of $14.00 Cdn, new, + $40 for the bullseyes lol.

i put a ulmer clutch kit and excell exhaust last year on my phaser fx, i added some holes to the airbox and it made a difference, the biggest gain i saw is when the motor started to losen up around 1000 mi., it seemed to run much better
