Item Description
99-00 Mazda Miata MX-5 1.8L NB1 Complete Set of 4 Piston & Rods BP4W 5881
Complete, assembled set of 4 pistons, rods and wrist pins from a 1999 Mazda Miata. The pistons skirts have some wear, scratches and scuffing, which has been detailed in the photos. The rings lands have no cracks, bent areas or any other damage. The rods move freely on the wrist pins and both ends of the rods are undamaged. These pistons are standard bore and 9.5:1 compression. The rings move freely and are unbroken but it is recommended they be replaced before use. As with any of our used engine parts, we recommend having these checked by a professional machinist prior to use. The images are of the actual items you will receive.
Fits 1999-2000 Mazda Miata as a direct replacement.
Also fits 1994-1997 NA8 and 2001-2005 NB2 Mazda Miata but the compression will be 9.5:1.

We accept all major credit and debit cards and the other payment methods shown at checkout, processed securely through Shopify. Payment is due in full at the time of purchase, and sales tax is applied where required.
For programmed ECU/ECM/PCM orders, be sure to submit your VIN, odometer reading, and current part number at checkout so we can program the unit before it ships.
We ship to all 50 states. Most orders leave our Hazelwood, MO shop within 1–2 business days by FedEx, UPS, or USPS, and you’ll get tracking by email as soon as it’s on the way.
Heavy items like engines, transmissions, and body panels may ship freight — we note that on the listing when it applies. Alaska and Hawaii have a flat-rate surcharge calculated at checkout. We don’t ship to PO Boxes or outside the U.S.
Local pickup is available at our Hazelwood facility by appointment — call ahead to set a time.
Returns are accepted within 60 days. A 20% restocking fee applies to standard returns, but it’s waived if we sent the wrong part, it arrived damaged, or it’s verified defective. Inspect your order on arrival and contact us within 7 days in those cases — we cover return shipping.
Programmed ECU/ECM/PCM modules are returnable only if defective, damaged, or incorrect. Because each one is programmed to the VIN you provide, we can’t take them back for compatibility issues from an incorrect VIN, odometer, or part number — double-check before you order.
Approved refunds are issued to your original payment method within 10 business days.
Every part carries a 60-day limited warranty against defects from the date it’s delivered. It covers manufacturing defects, parts that fail to function as described, and internal mechanical or electrical failure under normal use.
Not covered: damage from improper installation, accident, misuse, or modification; normal wear and tear; labor, towing, or rental costs; racing, off-road, or commercial use unless stated; and items with broken warranty seals.
