Spark plugs for your Suzuki PE175
The recommended plug is a BR8ES. Match that code - spark plugs are thread-, reach-, and heat-range-specific, so the part number matters more than the brand. Worth considering: the BR8HIX iridium upgrade - it fits the same port, fires cleaner, and lasts far longer between changes.

Frequently asked
What spark plug does a Suzuki PE175 take?
GarageDex's powersports data shows the Suzuki PE175 uses a BR8ES spark plug, gapped to 0.035", or upgrade to the BR8HIX iridium plug. Spark plug fitment varies by year - see the table for each range.
What is the spark plug gap on a Suzuki PE175?
The Suzuki PE175 spark plug gap is 0.035". Set the gap with a feeler gauge before install - iridium plugs come pre-gapped but always verify, since a wrong gap causes misfires and hard starts.
Are iridium spark plugs worth it on a Suzuki PE175?
The BR8HIX is the iridium upgrade for the standard BR8ES. It fits the same port and heat range, fires more reliably, and lasts far longer between changes - a worthwhile swap for most riders, though the standard plug is perfectly fine if you change plugs on schedule.
Does the Suzuki PE175 spark plug change by year?
Yes - the fitment differs across the years we cover: 2003 uses BR8ES; 1976-1977 uses BR8HS; 1971-1975 uses BR8ES. Match your exact year in the table.
How often should I change the spark plugs on a motorcycle?
Standard plugs typically want replacing every 8,000-12,000 miles (or per your service manual); iridium plugs go much longer. Fouled or worn plugs cause hard starts, misfires, and poor fuel economy - a cheap part that punches above its weight.
