The thread size of the oil drain plug on a Lexus IS350 is M12x1.25mm. When changing the OEM drain plug, a magnetic oil drain plug kit is a good idea. The magnetic oil drain plug provides extreme magnetism to remove all the metal particles in motor oil. It is a small but very useful component. A common misconception about the IS350 magnetic oil drain plug is that it is unnecessary since the oil filter is capable of catching any metal particle.

However, these tiny metal particles are about 25 microns and your oil filter can only capture particles larger than 35 microns. Even if you change the oil totally, there is still residue left in the engine. Over time, this contamination is circulated millions of times between each oil change, polishing down the metal components until the engine is worn out. As long as you are using a high-quality Lexus IS350 magnetic drain plug and correctly installed it, it makes your vehicle safer than the stock setup.

Why Choose a Lexus Titanium Magnetic Oil Drain Plug Kit?

In short, replacing the oil drain plug is not expensive, but it is very effective in increasing the performance and lifespan of your engine. BONOSS forged Titanium magnetic oil drain plugs are constructed from forged Titanium alloy and a powerful neodymium magnet. The Titanium alloys are light in weight as well as very strong. They feature great fatigue strength and tensile strength, hard, and high-temperature resistance. Even at extreme temperatures up to 400 to 500°C, they maintain great performance, preventing the plug bolt from loosening.

A thin oxide (TiO2, titania) layer spontaneously forms cover on the surface, which gives them extraordinary corrosion resistance ability. The magnetic part uses a high-strength neodymium magnet, which allows it to work well even in high-temperature conditions. It can operate in temperatures to 230°C, which is higher than most standard magnets which stop working at 150°C. The operating temperature for engine oil is between 90 to 110°C, and the BONOSS magnet oil plug will function in temperatures far past that of engine oil.
