XS Power RSV Titan8 Lithium Batteries

XS Power RSV Titan8 lithium batteries are designed to maximize capacity and deep cycling abilities. Part of XS Power's Lithium Titanate Oxide (LTO) Series, they have double the amount of storage energy but only half of the instant discharge energy, giving them double the capacity rating, but half of the wattage rating. The built-in 2/0 bussing allows up to four positive and four negative hidden direct connections to each module without the need for any external exposed bussing, while still leaving two easily accessible top terminals and four series or parallel expansion terminals to easily build a bank of nearly any configuration from 12 V, 24 V, 36 V, or any configuration imaginable. XS Power RSV Titan8 BCI direct-fit models are also available.

Denso Iridium TT Spark Plugs

Denso Iridium TT spark plugs, with their unique Twin-Tip technology, have two "tips": a 0.4mm iridium center electrode, and a 0.7mm platinum ground electrode. First used with OE spark plugs for luxury and performance cars, they are the smallest mass-produced center electrodes available. They require lower voltage and feature high-ignitability, so there is less interference with spark growth (quenching) and the twin tips deliver omnidirectional ignition, unlike the flat "sandwich" ignition of other spark plugs. Denso selected iridium and engineered it with rhodium to build the most durable alloy for spark plugs. Their patented formula has the highest concentration of iridium of any spark plug and even under the most severe engine temperatures resists oxidation and voltage wear for extended periods. The superior ignition of Denso Iridium TT spark plugs means more efficiency, fewer misfires, and significantly improved combustion, optimizing power and fuel economy like never before. Order the model designed for your vehicle application. Additional features of Denso Iridium TT spark plugs include: * Revolutionary 0.4mm center electrode means significantly improved combustion and reduced misfires * Invented by Denso, Iridium TT Twin-Tip technology creates a larger flame front for more complete combustion * Precision 360 degree laser-welding technology ensures structural support for the iridium center electrode, even in the harshest combustion environments * Tested to last well beyond 100,000 miles, with minimal loss of performance, for greater lifetime savings than any plugs available today

Denso Oxygen Sensors

Oxygen sensors, also known as Lambda sensors or O2 sensors, are among the most sensitive and critical components on your car's engine. They monitor the air/fuel mixture under idle, moderate acceleration, and cruise conditions. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio than the newer wide range air/fuel sensors (A/F sensors). Today's engines may use as many as four oxygen sensors to monitor exhaust gas oxygen content and catalytic converter efficiency. In order to perform these functions properly, Denso oxygen sensors adhere to strict OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt drivability and illuminate the check engine light, resulting in costly and time-consuming repairs. Denso First Time Fit oxygen sensors are designed to meet those tolerances and more. Key features and benefits of Denso Oxygen Sensors include: * Robotic laser welds * Porous PTFE filters block efficiency-robbing contaminants * Double-protection covers maintain proper temperature for quicker response times and protect ceramic elements from silicone and lead fouling * Rugged, watertight stainless steel housings resist corrosion and contamination * Aluminum oxide trap layers keep silicone and lead out, preventing damage to the platinum electrode * Refined zirconia elements improves sensor response * Superior design maximizes engine performance while reducing fuel consumption and harmful emissions * First Time Fit design delivers the right part the first time

Champion Platinum Power Spark Plugs

Champion Platinum Power spark plugs use a platinum pad welded to a nickel alloy center electrode for long life. Platinum has extremely good wear characteristics and can reduce gap growth. Champion Platinum Power spark plugs use a thin-wire center electrode with their exclusive Heat-Active alloy to reach operating temperatures quickly and maintain stable temperatures under varying engine loads. Because the plugs maintain the proper gap, the voltage needed to fire them remains consistent, reducing the chance of misfire. Get rid of those old spark plugs and try some of these Champion Platinum Power spark plugs for increased efficiency and reliability.
