- "Silvery air master!! Engine Jetras!"
- ―Jetras's roll call[src]
Engine Jetras (炎神ジェットラス Enjin Jettorasu?) is Go-on Silver's partner, a steamlined black/silver hybrid of a tiger (トラ, tora) and a fighter jet with a calm personality and ends his sentences with "Giin!" (ギーン！ Gīn!?) (an onomatopoeia of a jet flying by at supersonic speeds).
Before Speedor and the others were transported to the Human world, Jetras along with Toripter chased Land Pollution Vice-Minister Hiramechimedes into a wormhole that would expel the Wing Engines into the Human World where they would befriend their partners. After this meeting,the Engines brought the Go-on Wings back to Machine World where they would be mentored by Engine Jum-bowhale.
With his wings and amazing offensive abilities, he can fire the Jetras Torahawk (ジェットラストラホーク Jettorasu Torahōku?) cruise missile from the mouth. He can perform the Jetras Phantom (ジェットラスファントム Jettorasu Fantomu?), creating clones to confuse the enemy. He is split into two items when in storage, an Engine Cast and the number 8 Engine Soul. He is part of a pair with Engine Toripter. He can serve as an auxiliary attack arm for Engine-O and serves a similar function for Engine Gattai SeiKuu-O. To form Engine-O G9 he connects to Engine-O's left shoulder.
- In the Korean dub known as Power Rangers Engine Force, he is named Jetiger.
