Premiere Aviation now has 2 styles of Speed Covers; white gel coated and carbon fiber ones. They look amazing and the clearcoat shows the carbon fiber very nicely. Besides giving a different look they are clearly the best value in modification to your hydraulic gear Twin Cessna.

We have a few 425 Conquest owners who have posted the gains on Beechtalk; they are getting 268KTAS w -112's in cooler air and a whopping 285KTAS w 135A's.

It looks like they are getting about 5 KTAS increase at FL270. More importantly, the high altitude climb increase is huge especially when temp or torque limits power. No bleed off of speed needed, better block speed, overall gaining in all parameters of flight, net result will put a smile on your face.

Besides at the end of the day, you can load less fuel on and we all know how that goes too.

The best gainers in the Speed Cover aircraft are clearly the 414A and 421C where high altitude performance is just not that good when hot and when heavy. The covers work BETTER under these conditions. High altitude climb above FL200 is anywhere from 50-100% increase. We see climb of 500 fpm at 130 KIAS doing 195KTAS in the climb, leaned to 1450-1500 TIT. Speed increase at FL250 is a crazy 9-12KTAS. We have had many winglet equipped 421C's report on this and this is on par with all other reports.

The SE climb increase w an engine feathered over a 6-7 minute interval clearly shows a 25% INCREASE in SE climb. There is a realtime video on the website premiere-aviation.net.

With over 350 kits out there, it does what it is intended to and very cost effectively and is NON INVASIVE to install, 2 hours!

At the end of the day, a mod that saves fuel and will pay for itself, while increasing climb and cruise; and the least expensive mod and easiest to install, well that speaks for itself.

Worth the money, super easy to install, and reliable. No issues with the valve stem extender and the performance gain is noticeable.
