Arouse the DAMPFHAMMER!
Thanks for sharing this article. The K23A1 engine bypassed this forum, but of course we have some threads about it:
Insight to the k23a1 engine | Honda / Acura K20a K24a Engine Forum
Why no K23a1? | Honda / Acura K20a K24a Engine Forum
Further testing with the 2007-2011 Acura RDX platform, K23A1 (DYNO) | Honda / Acura K20a K24a Engine Forum
