NGK Spark Plug P/N:B9EG
NGK LFER7BHX spark plug for the 2017-2020 Audi A4 4-cylinder 2.0L and other vehicles ignites the air-fuel mixture in each cylinder. Like other NGK spark plugs, it threads into the cylinder head and carries the ignition spark across its electrode gap.
A rough idle, hard cold starts or a hesitant throttle response can mean a spark plug is worn, though a failing ignition coil or a vacuum leak can sit behind the same signs, so find the cause first.
NGK LFER7BHX is also a spark plug for the 2018-2020 Audi Q5 4-cylinder 2.0L, the 2013-2018 Volkswagen Jetta 4-cylinder 2.0L and the 2014-2018 Jetta 4-cylinder 1.8L.
