Fordman - Thank you! I checked and told the wrong manufacturer. They are Denso Iridium, Part # SK20HR11. Funny thing, I went to Oreillys for the SPs after Honda didn't have them
had to go to the corporate office in Springfield! No one keeps anything in stock around Southern Mizzou for the 1st Gen Insight.
Pete c - Thank you for the encouragement! I miss the Escort, I had A LOT of fun with that build. I'm going at the Insight with the same intensity, just slower as I don't have access to materials as readily in Mizzou than NC.
One of my main focuses on this build is going to be the same as the Escort - aerodynamics. The Insight is amazing in factory form, but as all vehicles, is a template for the artist to showcase his/her skills and talents.
I achieved an 18.5% reduction in drag on the Escort (0.33 to 0.269). The same on the Insight would give me a Cd of 0.204, which I think is achievable. My hypothesis is that Honda didn't do to well with the Insight. Phil Knox (Aerohead) has said repeatedly that 0.25 is the start of "Low Drag Territory". It makes sense for a manufacturer, even Honda, to achieve this mark and say "Good enough!" because it would look good for those who know what 0.25 Cd signifies.
