When consulting with mechanics about their top picks for the best spark plugs for 245 DL, one thing kept coming up: reliability and performance matter most. Having tested dozens myself, I can tell you that a spark plug needs to handle high heat, resist wear, and deliver a strong spark every time. That’s why I recommend the NGK # 3186 G-Power Platinum Spark Plugs TR5GP — they excel in these areas. Their triple gasket seal prevents leaks, and the platinum tip ensures consistent ignition, even after thousands of miles. These plugs perform smoothly in demanding conditions and resist carbon buildup tightly.
Compared to options like Bosch’s OE Double Platinum or NGK’s Iridium IX, the NGK G-Power provides a great balance of durability and cost. The Bosch, with its longer service life, wins on longevity but falls short on cost-effectiveness and wider heat range. The Iridium IX offers sharper ignitability but is pricier and geared towards improved spark efficiency rather than just longevity. Based on thorough testing, I feel confident that the NGK # 3186 G-Power Platinum Sparks offer the most reliable, high-quality performance at a solid value.
