Not sure it matters, but you can also get the new EXP119 in the NON Thunderbolt version (standard Lycoming). My buddy has it in the 14a.
There are quite a few changes. The Oil cooler is a bit changed. The Air intake is redesigned and also the the throttle body is now from Air Flow Performance. It's the gold looking thing on Dans picture.
The exhaust is different, hence the bottom cowl must be because of the new exhaust pipes.
The RV14a now has a cowl flap in the tunnel where the original exhaust was...
Based on the performance numbers. The difference is Huge!
