Have to agree with Pascall, AntiSplat has got some good gear, however you may consider
this Low Tech Low Cost mod, with care can be done on painted bottom cowl,
pic shows "letter box" vents in bottom cowl of an RV6. I did the same on
my flying RV10. Locate the three sided cut about three inches from the rear edge
of the bottom cowl, lift the front to clear the exhaust fill in the sides,
job done. This mod has been very successful in reducing OIL and CHT temps on two
and four place RVs here in WEST OZ by providing extra exit air flow. Other
advantages apart from being a home grown successful mod are, no observed speed
penalty, undetectable from the side of the aircraft, makes a handy hand hold
when fitting the bottom cowl, permenant no ongoing maintenance or extra wirering
and plugs. Cheers from Western Australia

I have a pair of AntiSplat cowl flaps installed in my 10. I'm not sure that
I would do it again if I were starting over. They were expensive (at $370
each), and both of the hinges ended up cracking due to the VERY tight
radius they bent into the aluminum piano hinge. I ended up replacing the
hinge with stainless hinge.
Maybe I'll be a little happier with them in a few months when the PITA of
replacing those hinges isn't as fresh in my mind!
As for cooling, I never had the stock louvers installed, so I can't compare
one to the other, but I can do full power climbs (at ~120kts) all the way
to 12k with CHTs staying below 400.

There's a guy @ DVT with a 10 that has them installed, I think he's happy
with them, but when I last spoke with him he was in the process of
replacing the mounting brackets that mount them to the cowl, apparently the
initial brackets were subject to some vibration cracks. He showed me where
they had cracked/broke in several places. I don't know his name, he's not
very chatty. His plane is the one with all of the military, Marine Corp and
Patriotic air brushed paint job.

Thanks Ed. Very helpful. I guess that shows the stock louvers are not that
effective. I was thinking of putting the cowl flaps outside the louvers. I
will have to but a 3-D template to verify muffler clearance, but looked
okay this morning, just eyeballing it.

I have the stock louvers installed and have had absolutely no temperature
issues on climb out. Friday I climbed straight to 11.5k at 120kts and none
of my cylinders even came close to 400.

I don't suppose you were starting from ground temps of 85-90, much less
departing with an engine that had already been hot soaked during a refuel
stop. I expect this weekend I will be doing at least on takeoff with
surface temps above 100.

Ed,
Have you happened to do a climb to altitude with the cowl flaps open, and an
other under the same conditions with the cowl flaps closed? Would love to se
e the results of that.
Thanks!
