  1. Great product 5 Star Review

    Posted by on Sep 10th 2018

    Works as it should, checked every spring fuel psi, right on the money


  2. More power smoother running 5 Star Review

    Posted by on Aug 20th 2018

    I have just installed the gold spring not long after the oil crossover pipe it has made it run slightly smoother again and quieter again on the hwy. Slightly more power and has smoothed the engine out right through the rev range . Even noticed less cackle another awesome product from riffraff.


  3. Works good. 4 Star Review

    Posted by on Jun 18th 2018

    I used the gold spring and it works good. Honestly can't tell much of a difference in power. Idle is a little smoother. Spring is definitely a little longer than the original I took out but went back really easy.

    Great product..


  5. Another great riffraff product. 4 Star Review

    Posted by on Jun 7th 2018

    Fuel system is much happier. Quieter injectors, smoother power curve, 1mg increase. I installed gold and have 175s, curious about black though.

    I only wish this kit was available with the special beveled o ring that seals the poppet.

    Overall very happy


  6. Works as advertised 5 Star Review

    Posted by on Jun 6th 2018

    I am running the recommended spring for my stock engine. It definitely quiet it down and smoothed out my idle I haven't hooked up a gauge to see what my fuel pressure is. I would recommend it


  7. Bought 2 sets great difference 5 Star Review

    Posted by on Apr 29th 2018

    The install is easy I ran the black springs in the truck with less mods. And ran the
    Mid spring in my other. The throttle response all of them was better and a little more crisp. I will be buying a third set. Worth the small price!


  8. What a difference. 5 Star Review

    Posted by on Mar 19th 2018

    I installed the gold spring on my 02 7.3l and wow. It has a much quieter idle as well when in high rpms (above 2000rpm) and throttle response is amazing! I went out and tested it. Floored it at a light and it took off quick! Much better than before.
