Thanks for the great directions. Did it myself this morning and it took about an hour all told. Note: Watch the wire clip on the injectors, and note how it fits as between the two injectors, it is bound to fall off at least one - it did on both of mine. You will have to reinstall it via Braille as you cannot see it, but it is no big deal, just feel for the posts it clips over and you will be fine. OP, did you replace the metal hose clamp on the vent hose when you replaced yours? Since it was a one-shot crimp-type, and I noticed it missing on your photo, I left mine off as well. No problems, started right up, and idles fine. Haven't taken it out yet for a spin, so it will be interesting to see how it runs with the TuneBoy 0205 program, the MWR filter (with accessory plate kit which by the way, is nothing more than 4 small bolts, 4 springs, and 4 locknuts, costing $44) plus the Termi slip-ons. May switch the ECU over to Wayne's version of the full Termi ECU program if it feels lean. I'll let you all know.
Update: took it out for a 10 mile run through traffic, and up the freeway. Seems to idle a bit smoother, maybe, and "pops" when shifting a bit less (does that mean it is a little less rich than before the MWR filter?), and on the freeway with light throttle, maybe a bit smoother, but nothing that smacks me upside the head and says "who added a bunch of power here". Does not appear to want to wheelie any more than before, but doesn't run any worse either. All part of the package of airfilter, ECU, and Termi exhaust, to prepare for a proper dyno tuning, so we shall see.
