2002 VFR, 46k miles, running very poorly when hot. in Sixth Generation VFR's Posted July 27 42 minutes ago, Cogswell said: FWIW, Honda coilpacks are made by Denso and are of high quality. Failures are rare. If replacing though, those used on the VTEC engine are the same ones used on many Honda / Acura automobiles - CRV, Civic, RSX and others. Find the Denso part number and do a search - you'll tons of them on ebay or elsewhere - you do not need to buy them from Honda Powersports. Just curious - why has your flapper valve been deactivated? Good to know on the coil packs. If I end up replacing those I'll check around. I did the intake snorkel delete and flapper valve mod because it sounded better, pure and simple. I wanted some more intake growl. It didn't seem to affect the bike really other than sound and it's run well for years prior.
