Why this one
Purpose-sized for common manifold studs
The 13 mm capacity targets the fastener diameters found most often on exhaust manifolds, intake plenums, and turbo flanges.
Compatible with any 3/8 inch drive handle
Attach this tool to your preferred ratchet, breaker bar, or torque wrench and apply smooth rotational force.
Internal gripping mechanism
The tool bites into the exposed portion of a stud as turning force is applied, locking tighter with each degree of rotation.
Sold individually for working professionals
Technicians who service the same vehicle platforms repeatedly know which stud sizes they encounter most.
Exhaust and engine work made simpler
Seized exhaust manifold studs are among the most common extraction jobs in any repair shop.
Read the full description
Exhaust manifold studs, intake bolts, and turbo-flange fasteners in the 13 mm range are some of the most frequently seized hardware in automotive repair. Heat cycling and corrosion weld them into their bores, and a slipped wrench or broken stud turns a routine job into a time-consuming ordeal.
This 13 mm extraction tool grips the exposed portion of the stud with an internal mechanism that locks tighter as you turn. Attach it to any 3/8 inch drive ratchet or breaker bar, apply steady rotational force, and the tool does the rest. No welding, no drilling, no re-tapping — just controlled removal.
The 3/8 inch drive interface means you use handles you already own. Flex-head ratchets work well in tight engine bays, while a long breaker bar adds the leverage needed for heavily corroded fasteners. Whichever handle you choose, the connection is universal and secure.
Sold as a single tool, not a kit. Buy the one size your job demands. If you already carry a multi-piece extraction kit, this is the replacement for the piece that wore out first — the one you used on every other car that rolled into the bay. Stocking individual sizes on your cart means the right tool is always within reach.
Teng Tools builds hand tools for tradesmen who need reliable, purpose-built equipment on every job.
