What It Is

This S100 oil change kit includes an oil filter (AM125424), air filter (MIU14395), and spark plug for John Deere 100 Series lawn tractors (D100–D140, E100–E140, S100–S140) and Z300 Series zero-turn mowers (Z315e, Z335e). It’s designed for a single oil change and tune-up, replacing three common wear items in one box.

Fitment & Compatibility

Before buying, confirm your mower’s model and engine type. This kit fits John Deere 100 Series tractors (D105, D110, D125, D130, D140, E100, E140, S130, S140) and Z300 Series (Z315e, Z335e) with Briggs & Stratton or Kawasaki engines that use AM125424 oil filters and MIU14395 air filters. Check your owner’s manual for the exact filter and spark plug numbers—this kit is aftermarket, not OEM John Deere. Measure your air filter (approx. 4.5 x 2.5 inches) and oil filter (approx. 3.5 inches tall, 2.5-inch diameter) to verify. Not for older or non-listed models.

Key Things to Know

• Quality is decent for the price – These are generic replacements, not OEM. Expect average lifespan; some users report air filter fit is slightly loose.
• Installation is straightforward – No special tools needed: drain oil, replace filter, swap air filter and spark plug. Takes 20–30 minutes.
• Watch the plug gap – The spark plug may not come pre-gapped. Check gap with a feeler gauge (typically 0.030 inches) before installing.
• Compatibility gotcha – Double-check your engine’s oil filter thread size (3/4-16 is common) and air filter shape. Some 100 Series models use a different oil filter (e.g., AM125424 vs. AM107756).

Should You Buy It

Buy this kit if you want a low-cost, all-in-one tune-up for a John Deere 100 Series or Z300 Series mower and don’t mind aftermarket parts for routine maintenance. It’s a solid budget option for DIYers, but skip it if you prefer OEM reliability or have a non-standard engine—verify fitment first to avoid a return.
