    MMR head cooling mod for sale

    I've sat and looked at this long enough. It's new in the box and includes everything you would get from mmr. It is the one that goes on the back rear of the heads.
    They are out of stock and 199.99 plus shipping. I'll do 180 shipped if you cover pp fees or gift. I'll text pics if you need em.

    Is the MMR a better quality cooling mod than the Lethal Performance one? What is everyone's opinion?

    They all do roughly the same thing. It's personal preference.
    You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference

    I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

    Personally, I went from the oem style right side tube, and modified a second tube for the drivers side head. It's been this way for a year and I originally thought one developed a leak so I ordered this kit instantly. I should have looked a little harder as it was actually just a failed hose clamp.
    I already had the thing apart and could have actually used the mmr kit as the work was already half done, but chose not to based on the fact the oem port is 3/4 and is designed for a single heads amount of flow. The mmr kit is not only 1/2 inch and uses an adapter to get back to 3/4, but it combines both heads through the 1/2 inch line.
    Obviously this isn't a problem as the kit has been on and worked for hundreds of high hp systems, but I decided to stick with a dual 3/4 setup. Just felt better about it.
