Eli R. ★★★★★

The mandrel-bent tubing made installation straightforward on my 2006 Altima, and the fit was perfect out of the box. After three months of daily driving, the check engine light hasn't flickered once.

Evelyn ★★★★★

The check engine light finally stayed off after I swapped this in on my Altima. The mandrel-bent tubing made installation flow much smoother than the stock piece I was wrestling with, and the corrosion resistance gives me peace of mind for the salty winter roads.

Lily ★★★★★

The install on my 04 Maxima was straightforward, and the CARB compliance sticker gave me peace of mind for smog check. It's been a few months now without any check engine light issues.
