Spark Plugs - Acura Integra 1987 Manual

Spark plugs should be replaced every 24 months or 30,000 miles
(48,000 km), whichever comes first.
Recommended spark plugs:
BCPR6EY-11 (NGK), BCPR6EY-N11 (NGK), Q20PR-U11 (ND)
(for all normal driving)
BCPR7EY-11 (NGK), BCPR7EY-N11 (NGK), Q22PR-U11 (ND)
(for hot climates or continuous high speed driving)
BCPR5EY-11 (NGK), BCPR5EY-N11 (NGK), Q16PR-U11 (ND)
(for cold climates)
CAUTION: Never use spark plugs with an improper heat range;
they will adversely affect engine performance and durability.
Replace plugs one at a time, so you don't get the wires mixed up.
1. Clean any dirt from around the spark plug base.
2. Disconnect the plug cap, then remove and discard the old plug.
3. Check the gap of the new spark plug before installation. Plug
gap should be 1.1 mm (0.04 in).
4. Thread the new spark plug in by hand to prevent cross­
threading.
5. After the plug seats against the cylinder head, tighten 1/2 turn
with a spark plug wrench to compress the washer.
6. Reinstall spark plug cap.
CAUTION: The spark plugs must be securely tightened, but not
overtightened. A plug that's too loose can get very hot and
possibly damage the engine; one that's too tight could damage the
threads in the cylinder head.
