I just installed my XS headers and im stuck on which to do next. Should I go with this NOPI series AEM CAI or the UR Ultra S Crank pulley next? The CAI is $172 shipped and the pulley is $183 shipped. Which would makes the biggest difference do you think?

Edit: Anyone know where to get either for a better price?

 

headers and intake will work best together, so i would highly recommend doing that first. i just tried to get my pulley installed but the shop owner doing my 105k workup wouldn't do it because he couldn't use the honda tool to tighten the nut

but yeah, intake first, pulley second.

 

We sell the UR pulley for $180 shipped.
