Not worthwhile. CR9EIX is the same plug but without the 1mm extended tip that the CR9EIA has, and you can get or order the CR9EIX from *any* NGK dealer. They cost way less, and as far as I can tell, there's no difference in operation ... Heck, if you want the CR9EIA-9, you can probably order those from an NGK dealer, too.
Canadian Tire, UAP/NAPA, etc all deal with NGK.
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
