15.5v regulator replacement for denso hairpin alternators

Charges at 15.5v shortly after install i was right at 15.5v!

After switching from diodes I really like this product because it doesn’t fluctuate my voltage it stays in the 15.3 to 15.5 range.

Maybe its my car but the only time I see 15.5 is when its cold outside. I like this product because my voltage stays the same.
