This product line is tailored to maintain ignition efficiency over time, reducing the need for frequent replacements while supporting stable engine operation in compatible Suzuki models.\u003c\/p\u003e\u003ch2\u003eTechnical Details and Features\u003c\/h2\u003e\u003cp\u003eThe Denso 3449 spark plug features an iridium center electrode tip, which offers a fine wire design that requires less voltage to produce a strong spark. The copper core center electrode enhances electrical conductivity, improving ignition response. The ground electrode incorporates a platinum chip tip, which increases electrode life by resisting erosion. The single ground electrode with a standard configuration ensures consistent spark gap maintenance. With a pre-gap size of 1.1 mm and a flat seat design, this spark plug fits securely and delivers reliable combustion. The 16.0 mm hex size allows for easy installation using common tools, while the 14.00 mm thread diameter and 19.00 mm reach ensure proper fitment in Suzuki Esteem, Grand Vitara, Vitara, and XL-7 engines.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestores stable ignition in Suzuki Esteem and Grand Vitara engines\u003c\/li\u003e\n\u003cli\u003eReduces misfires and rough idling in Vitara and XL-7 models\u003c\/li\u003e\n\u003cli\u003eImproves fuel efficiency by ensuring complete combustion\u003c\/li\u003e\n\u003cli\u003eMinimizes electrode wear for extended spark plug life\u003c\/li\u003e\n\u003cli\u003eHelps maintain engine performance under varied driving conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the spark plug gap is set to the specified 1.1 mm pre-gap before installation. Use a 16.0 mm socket wrench for proper tightening to avoid damage to the electrode or threads. Confirm compatibility with Suzuki Esteem, Grand Vitara, Vitara, or XL-7 models prior to installation.
