Engineered with a fine iridium tip, these plugs provide a consistent and reliable spark, enhancing engine responsiveness and throttle performance. The tapered cut ground electrode improves starting and idling, making your vehicle run smoother and more efficiently. With a higher melting point due to iridium alloy construction, these plugs are ideal for modern engines demanding superior heat resistance. The trivalent metal plating offers excellent anti-corrosion and anti-seize properties, ensuring easier installation and longer service life. Suitable for modified or high-performance applications, NGK Iridium IX plugs are an upgrade over standard nickel alloy options, especially in performance-oriented vehicles. These plugs are recommended for 2014-2015 Cadillac CTS and XTS models, with a colder heat range than original equipment to maximize performance without risking pre-ignition or fouling. Their robust design and advanced materials make them a top choice for enthusiasts seeking improved engine response and efficiency.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eOptimized for high-performance applications and vehicle upgrades\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIridium fine wire center electrode for enhanced durability and consistent sparks\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTapered cut ground electrode for better starting, idling, and throttle response\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTrivalent metal plating provides superior corrosion and anti-seizing benefits\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eColder heat range than OEM, suitable for modified engines\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n2014 Cadillac CTS Vsport\u003cbr\u003e\n2014 Cadillac CTS Vsport Premium\u003cbr\u003e\n2014 Cadillac XTS Vsport Platinum\u003cbr\u003e\n2014 Cadillac XTS Vsport Premium\u003cbr\u003e\n2015 Cadillac XTS Vsport Platinum\u003cbr\u003e\n2015 Cadillac XTS Vsport Premium\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbdoy\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Unknown\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: t\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 4\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbdoy\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"NGK","offers":[{"title":"Default Title","offer_id":53618473664785,"sku":"6510","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/3830\/0689\/files\/49be3f5efa6eeb6f0e22a3c194bc846b.jpg?v=1780503119","url":"https:\/\/shoprenegade.com\/products\/ngk-iridium-ix-spark-plugs-for-cadillac-cts-and-xts-part-number-6510-pack-of-4","provider":"Renegade Speed by Renegade Racing \u0026 Performance","version":"1.0","type":"link"}
