Frequently Asked Questions about Aircraft Engine Baffles


When do I need to replace my engine baffles?
When the old ones begin to lay over and no longer create positive air flow through and around your engine cylinders which would cause improper cooling resulting in increased engine temperature.
What is the difference between the Silicone and Neoprene material?
The major difference between the two is the temperature rating. Silicone is rated up to 550 F & Neoprene is rated up to 212 F
Should I choose textured or smooth material?
The textured material is designed for heavy duty use with a longer life. When manufacturing the textured material, we use a fiberglass reinforcement mat that is several times heavier that the one used in the smooth finish. The heavier mat is going to give, and provide a much greater reinforcement protecting the material from tears, and allowing it to hold form and fit in a manner resulting in a much more efficient functioning product. However, this adds additional weight, so some customers choose the smooth engine baffles for that reason.
Does engine baffle have to have fiberglass reinforcement?
Yes. Fiberglass reinforcement prevents the baffle material from rips and tears which keep the baffle from functioning correctly.
How do I attach the new Baffle material?
We have a two piece engine baffle fastener T-3700-3-Pk that only requires a screwdriver to install or you may use a large flange rivet with a backing strip.
How do I cut the baffle to fit?
Remove the old baffles without destroying them, and use them as a pattern for cutting the new baffles. Be sure to allow extra when cutting the new ones and make notes of where extra is needed before removing the worn ones.
