Product details
Built to OE standards in Japan, the NGK PFR7B is the ignition plug for the BMW Alpina B7 from 2007–2008, firing the air-fuel charge in each cylinder. It matches BMW part number 12120035747. A spark plug's job is to jump a high-voltage spark across its gap at exactly the right moment, and it does this through countless ignition cycles. Over that time, deposits from fuel and oil can build up on the electrode and weaken the spark. Worn plugs can leave the engine down on power, cause misfires, and hurt fuel economy.
NGK spark plugs sold by PMB Performance carry a 24-month / 24,000-mile warranty.
NGK designations follow a code. In PFR7B, the number 7 is the heat range, so match that number when comparing plugs and do not mix heat ranges in one engine. The BMW cross-reference 12120035747 is the quickest check against the plug BMW specifies for your car. Replace plugs at the manufacturer's service interval, and check their condition when you pull them for any warning signs. NGK has supplied spark plugs since 1936 and sells them to vehicle manufacturers as original equipment as well as to the aftermarket, under its parent company Niterra of Nagoya, Japan.
