GROUP BUY: 1NZ to 1ZZ TB spacer/adapter - Toyota Yaris Forums

MGargano · 07-27-2010, 09:33 PM

I've had the 1ZZ TB and spacer setup installed for about 3 months so far. To be honest, I feel no difference in performance when using the spacer. It seems to reduce the 1ZZ down to a 1NZ, as I believe someone pointed out earlier in this thread.

When I had the 1ZZ installed previously, with no spacer, I felt a definite and measurable increase in performance. All I see now is a high cold idle and a jerky-ness when I let off the gas. I've had no CEL and no oscillation though, which is a perk I guess.

I don't know if my results are the same as everyone else who is using this spacer. I'd be interested to hear other reviews.
