I have a 2002 model FD. OEM Twin Turbo. 16bit harness.
I need new spark plug wires. Do I need to get 16bit-specific plug wires? or are all the spark plug wires compatible with all year/bit-harness FD's?

If I need specific 16-bit wires, where can I get them and what do you recommend ?


Thanks.

 

16 bit ones have slightly longer leadings due to the positioning of the leading coil on the end of the pack (early cars have it in the middle).

 

Ah, thanks. So they need to be a little longer in length to fit. Thanks.
Any suggestions on what brand type I should buy and where?

 

Short of finding a cache of NOS N3A1 OEM leads, that someone has salted away for decades, you'll probably only find the equivalent of the late N3F1 ones anyhow. That's all that's sold here at least and usually listed as universal.

If NGK floats your boat - and I assume they've got a distributor there, I'd look for RC-ZE52.

 

Awesome, thank you 🙏🏼😊

 

To ensure compatibility and optimal performance, it's advisable to use spark plug wires designed for your 2002 Mazda RX-7 FD with a 16-bit harness.
