This is a replacement set of exhaust manifold studs and nuts for your Sonic/Cruze/Trax/Encore 1.4T engine made from grade 5 titanium. Titanium offers superior corrosion resistance over steel and stainless steel, all while being lighter and significantly stronger as well. Never have to worry about a broken or corroded stud again, these titanium components will outlast your engine.  

Includes:

• (8) titanium studs
• (8) self locking titanium 6 point nuts

These use an E7 socket for installation, use factory torque specs. Studs are M8x1.25 just like factory. 

Fits: 2011-2016.5 Chevrolet Cruze 1.4T, 2012-2020 Chevrolet Sonic 1.4T, 2013-2021 Buick Encore 1.4T, 2015-2021 Chevrolet Trax 1.4T.
