Love your Piper but wish it could do a little more?
The Piper PA 28, 32 and 34 series of aircraft are world renowned for their durability and overall reliability, but they weren’t built to maximize performance.
Fortunately, there are a number of cost effective aerodynamic improvements that we developed that can easily add 3 to up to 15 MPH, while also improving rate of climb, slow speed handling (reduced stall speed, improved aileron control) and save you fuel.
Laminar Flow Systems, Inc. has been manufacturing and selling these modifications since 1984 and we have thousands of satisfied customers worldwide. We invite you to look around and come see why we have the best made, lowest priced and best warranty of any modifications available for your Piper.

What Our Customers Say
there is a definite 15-knot increase…The numbers show that it has paid for itself in one year.
I could not believe the difference. My performance improvements are way beyond anything I expected.
The installation was straight-forward with no surprises
The performance change has been incredible…I can’t begin to explain how different the plane feels.
I see no one else other than Robin Thomas who makes a promise that if you’re not satisfied, no questions asked, you get your money back.
I get approximately 200 feet per minute in climb increase and 15 knots in cruise. I know that I could save fuel instead of the extra speed, but I really enjoy the speed. I guess that explains why I have had the same plane for 30 years!
There is no doubt that your kit was responsible for our taking second place in the race.
It had never lifted off that easily before…I am now climbing faster with a solid feel to the controls and the ride.
