Customers appreciate the product's practicality, affirming it aptly suits LS swaps to substitute factory allen plug with temperature sensors. Reviewers commend its perfect fit and usability, stating it effortlessly accommodates 1/8 npt fan switches and dash gauges. Unlike competitor products, it resolves the issue of losing an ECM input. However, caution is advised as a few users notified about the center hole being unaligned, potentially leading to damage. Despite these rare cases, numerous customers would repurchase if necessary given its performance, quality, and valuable solution it imparts to specialized problems.

Perfect part & [...]low cost!
This is the only fitting to get from metric to NPT to adapt the water temp gage. If you try to use one of the head ports you will lose an input to the ECM and really screw things up! This solved the problem, Neithor Jegs or Summit had it or could help me with the problem and technical advise to avoid the ECM problem. I would have never figured it out! Thank you!

Poor quality, broke in cylinder head
The hole in the center was not drilled straight (was offset to the centerline), and wouldn't allow the sending unit to screw into the adapter. After drilling the hole straight, once I tried to tighten the adapter, it broke off in the head! I had to re-drill and tap the head, which was a HUGE pain in the rear. If I could give this negative stars, I would have.

Fits in passenger head in place of factory Allen plug to add temp sensor like on the drivers side but for an aftermarket gauge neat and out of the way no hose splices

When screwed into the adapter, how much of the temperature probe on the S-W 280EA sensor is exposed to the water (past the adapter's tread-end)?
