SkyGeek likes to seek out how the products we sell are made, products like the Tempest® URHM38S Fine Wire Aviation Spark Plug. Otherwise, we'd be ignorant and ignorance leads to poor purchasing decisions.
Tempest's® spark plugs are well made and designed to make the sparks fly…and you as well. We're all visual learners so let the following video show you the type of craftsmanship embedded in the URHM38S:
Also, for your viewing pleasure are a multitude of features and specifications listed on this page.
High Conductivity Copper Core Center Electrode: Copper, co-extruded inside a nickel alloy sleeve ensures outstanding heat and electrical conductivity while the nickel sleeve offers high resistance to corrosive combustion gases.
High Alumina Ceramic Insulator: High mechanical strength, superior dielectric properties, proprietary protective glaze, provides high performance to conquer severe operational conditions. "Clean Collar" massive electrode "V" tip focuses heat to reduce fouling and enhance heat range control.
Proprietary Glass Center Seal: 21st century 'fired in' resistor replaces the multipart screw, spring, carbon pile stack up used in competitive plugs and known to suffer from resistance value instability that can cause misfires, wasted fuel, engine roughness.
Nickel Finish: Environmentally preferable electrolytic nickel provides outstanding durable finish, superior corrosion protection, and extreme wear resistance.
Nickel Ground Electrodes: Aviation grade nickel electrode design focuses on minimizing sparking voltage requirements while maintaining specification gaps to ensure large, stable 'flame kernels' for on-time ignition and complete combustion.
Vacuum Infused Center Electrode: Proprietary, vacuum infusion process seals electrode/insulator gap providing stable heat range and superior center electrode cooling (heat flow to the insulator).
Hot-Lock Assembly: Intense pressure and heat create positive, zero-leakage, shrunk in seal between insulator and shell to contain the hot, high pressure combustion cycle gases.
Harness Wire Contact: Smooth, uninterrupted, oxide treated spring contact surface offers enhanced corrosion resistance, is chemically bonded to the fired-in resistor providing the ultimate harness/spark plug termination integrity and energy transfer.
Thread size: 18 mm Reach: 1/2"/1.27 cm Shielded Threading: 3/4" - 20 Standard Electrode: Single Fine Wire Fine Wire Electrode: Iridium Plug Gap: .017"-.021"/0.42-0.53 mm
NOTE: Spark plugs are shipped in factory sealed plastic cases. Opened spark plug cases make the spark plugs non-returnable. Please do not open any spark plug until you are sure you have received the correct spark plugs for your application.
Overall Rating for Tempest URHM38S Fine Wire Aviation Spark Plug
I have a Mooney with a TSIO360-MB engine with Slick mags. Starting was not always smooth and that made both me and my passengers unhappy. The fine wire plugs really improved starting (fewer blades before starting) and hot starts are easier also. Happy and recommended.

If the item that you are trying to ship is deemed Hazmat you may have an additional fee added to your order when you check out. Items are deemed Hazmat as per the Section 14 Transport Information located in the item's Material Safety Data Sheet (MSDS). Sorry, but things that can go "boom" are hard to ship and we have to pass on our fees.
Flammable or explosive items such as Fire Extinguishers, MEK, Toluene, Paint Thinner, etc. are subject to a $25.00 Hazmat fee via ground shipping methods. However, the majority of Hazmat items have no fee when shipping with a ground method.
Most Hazardous Goods are subject to air and international transport fees. This fee is $40 for domestic air shipping methods and $80 for international shipping methods.
