Yep, they likely are stock...but only for your model year. Toyota used a slightly different igntion system for '94 model 22REs. And I see yours is a '94. I'm not sure what the other differences were, but one of them was smaller/thinner plug wires and I believe a different type of connector to the cap.

If I recall correctly, and I could be wrong, this system was prone to problems and Toyota reverted back to the old style ignition for the '95 model year, before switching over to Tacoma production.


The thinner plug wires were used on '93 models also. Yes they are OEM.

I've also heard that '94-95 models seem to have the timing chain failure problem happen a little earlier than prior models. I've heard of one '94 chain needing replacement at just over 60K miles and another at well under 100K. So, keep a close eye on yours, unless the chain/guides have already been changed.


What would cause this?

'04 Taco x-cab 3RZ FE stock (daily driver)
'90 x-cab 22RE stock
'82 Hilux 6" lift (ACES HI)
'82 2-Hiluxs' Rally Edition (parts)
'81 Hilux 3" lift (parts/restore)
