Mega Exhaust Spring, Engine to Manifold (4x30mm) (6)
MEG2682
Pack of six high-tensile steel exhaust springs (4x30mm) for .21 and .12 RC nitro engines, designed to securely connect the exhaust manifold to the engine crankcase, resisting extreme heat and vibration for leak-free performance in high-RPM racing.
Fortify your nitro engine's exhaust connection with this 6-pack of 4x30mm steel springs, precision-wound for maximum tension and corrosion resistance. These compact springs hook between the manifold flange and crankcase ears, maintaining airtight seals even with high exhaust temps and brutal track vibrations—preventing power-robbing leaks and ensuring consistent back pressure for optimal torque and RPM. Ideal for quick manifold swaps or rebuilds, they outlast stock springs for reliable starts and sustained performance. Genuine Serpent Mega replacements; stock up for pit-side peace of mind and race-winning exhaust integrity.
