If you want a direct, cost-effective replacement for your specific GM vehicle's oil drain system, choose TSIEBRV M14×1.5; if you need advanced engine protection with magnetic filtration and a broader fitment range for general automotive or marine repairs, choose Hacqicy M16.
• TSIEBRV M14×1.5: The standout strength is its precise OEM-level compatibility with Chevrolet, Buick, and Cadillac models from the 2010s, offering a simple bolt-and-gasket solution that mirrors the factory design. Its biggest trade-off is the lack of specialized features like magnets, meaning it offers no active debris filtration beyond what a standard filter provides. This pick is for owners of GM vehicles who just need a reliable, direct swap to get back on the road.
• Hacqicy M16: Its primary advantage lies in the built-in strong magnet designed to trap ferrous metal particles, actively protecting internal engine components during every oil change cycle. The trade-off is the larger M16 thread size, which limits its use to vehicles specifically matching that pitch rather than being a universal drop-in for older GM engines. This pick is for DIY mechanics looking for enhanced engine longevity and a service kit that includes multiple copper washers for repeated maintenance.
This component is engineered for a very specific group of vehicle owners who rely on the original equipment manufacturer (OEM) specifications for their daily drivers. The thread specification of M14×1.5 matches the factory requirement exactly, ensuring that when you reinstall the plug after an oil change, it seats correctly against the oil pan.
The design prioritizes simplicity and direct replacement over added complexity. It comes as a single unit with a galvanized carbon steel body and an included O-ring rubber sealing gasket. The galvanized finish is intended to provide resistance against rust and corrosion within the hot environment of an engine compartment, while the O-ring compresses to fill the gap between the plug and the pan, preventing leaks.
You should buy this product if you are performing a standard oil change on a compatible General Motors vehicle and want a part that replicates the original function without introducing new variables. However, if your vehicle requires an M16 thread or if you are working on a non-GM platform like a motorcycle or a boat, this specific thread size will not work, and you would need to look elsewhere. It is a straightforward tool for a straightforward job: replacing a worn-out drain plug with a durable, rust-resistant alternative that seals effectively using a rubber gasket.

The Hacqicy M16 is built for those who view oil changes as an opportunity to proactively protect their engine's internal health, rather than just completing a necessary maintenance task. The defining feature here is the integrated strong magnet, which serves a functional purpose beyond holding the plug in the hole. As oil circulates through the engine, microscopic iron shavings and metal filings can accumulate, potentially causing abrasion over time. This plug captures those fine ferrous particles, keeping them suspended in the plug itself rather than allowing them to recirculate through the engine block.
Constructed from stainless steel, this unit aims to maintain structural integrity under the high pressure and extreme temperatures found inside modern engines. Unlike the rubber O-ring found on the TSIEBRV model, the Hacqicy relies on five copper washers to create a solid seal. These washers are designed to compress evenly, filling micro-gaps between the plug and the oil pan surface to ensure a leak-free connection. The inclusion of five washers in the package suggests this kit is prepared for multiple service intervals, allowing you to replace the washers each time you change the oil to maintain that tight seal.
This product is ideal for DIY enthusiasts working on a wider variety of platforms, including cars, motorcycles, and boats, provided they share the M16×1.5 thread pitch. It is also a smart choice for anyone who wants to extend the life of their engine by reducing metal-on-metal wear caused by contaminants. You should skip this option if your vehicle specifically requires the smaller M14 thread, as the larger diameter simply will not fit into the oil pan. It is a more robust, feature-rich solution for those willing to verify their thread size before purchase, offering a complete service kit approach to vehicle maintenance.
• Best for Specific GM Models → TSIEBRV M14×1.5, due to its exact compatibility with Chevrolet, Buick, and Cadillac models from 2011 to 2021.
• Best for Engine Protection → Hacqicy M16, because the magnetic core actively traps metal debris that standard filters miss.
• Best Seal Material Preference → TSIEBRV M14×1.5 for those who prefer a rubber O-ring, versus Hacqicy M16 for those who trust copper crush washers for a reusable, hard-seal solution.
• Best for Versatility Across Vehicles → Hacqicy M16, as it fits a broader range of automotive, motorcycle, and marine applications sharing the M16 thread.
• Best Value for Service Kits → Hacqicy M16, since it includes five copper washers, providing consumables for multiple oil changes out of the box.
• Best for Rust Resistance → Both offer durability, but TSIEBRV uses galvanized carbon steel while Hacqicy uses stainless steel, both suitable for harsh environments.
• Best for Direct OEM Replacement → TSIEBRV M14×1.5, as it mimics the original design with a single gasket rather than a multi-washer setup.
For my own garage, when I am tackling DIY repairs on a classic GM sedan or crossover, I would reach for the TSIEBRV M14×1.5. There is no need to overcomplicate a repair that was designed to be simple; getting a plug that matches the original dimensions and seals with a standard O-ring ensures peace of mind that nothing will go wrong during reassembly. However, if I were maintaining a vintage motorcycle or a newer car where I wanted to maximize engine life by filtering out metal particulates, the Hacqicy M16 becomes the clear winner. The magnetic capability and the inclusion of spare copper washers make it a superior long-term investment for proactive maintenance, even though the thread size limits its universal application. Ultimately, the decision rests entirely on whether your vehicle needs the specific M14 thread or if the M16 magnetized upgrade is worth the search for the right fitment.
No, it is specifically designed for the M14×1.5 thread found in select models like the Sonic, Trax, Cruze, Volt, Encore, and ELR between 2011 and 2021. Always check your vehicle's year and model against the list before purchasing.
The built-in magnet traps fine ferrous metal particles that circulate in the oil, preventing them from causing abrasion to internal engine components, a benefit that standard non-magnetic plugs do not offer.
While the stainless steel plug is reusable, the copper washers are designed to deform slightly to create a seal, so using fresh washers from the included set of five for each oil change is recommended to prevent leaks.
The TSIEBRV uses a single O-ring rubber gasket to seal the joint, whereas the Hacqicy utilizes five copper washers that compress to fill gaps, offering two distinct approaches to preventing oil leaks.
