Microtube parallel flow is all I have used in the past ~5-10 years. They are much thinner and are much more efficient. A microtube parallel flow that is 1/3 the thickness of the OE style serpentine condenser will easily out perform it. The thinner parallel flow will also more airflow through the whole cooling stack as it is much less restrictive to airflow through it. The condensers on both of my vans and my Tahoe are only 5/8" thick and work exceptionally well even on a 115F day.For serpentine condensers I found OSC 4544 to be closest in thickness to original. It is slightly larger than 4721.
I have used the OSC 4721 on several SUVs and trucks. It is a mictrotube parallel flow and my aunts Escalade I put the last one on dropped 50 psi on the high side compared to what it ran in the same heat with the stock condenser. I also replaced the dying condenser fan on it.
