Supertech now offers a performance dual & single valve spring and retainer kits for the Mitsubishi 4G63 EVO engine.

Supertech Single/Dual Valve Springs:
Supertech performance valve springs are made with premium Superclean Chrome Silicon Vanadium Steel Alloy for higher performance and durability. Computer designed to ensure that wire stress levels do not overpass the limits for long durability under extreme conditions and harmonics are well under control.

Supertech Spring Seat Locater
Supertech spring seats are made from high grade steel and aide in the upgrading to dual valve springs. Thickness of spring seats may vary.

      Decent choice but still not real sheepskin, hence the price.
      Size: 2' x 6' (Oblong)
      Like it very much and am using it on a massage table for clients. Cozy and well priced this one, just know it’s not real and does have synthetic fibers throughout.

      Soft & fluffy. Stuffy arm rest.
      Color: Purple, Color: Purple
      Soft and fluffy & my fav color purps. Now I'm looking for other purple accessories to go with my 2021 Honda CRV. I don't think this cover would be be enough for a large SUV arm rest such as a Navigator... But yea, order if you want some color & funk in the ride

      Return refund impossible to receive also it’s tacky looking
      Color: Black
      First off this item said it was fit, but it did not second of all I went to return it and they could only be returned to the original payment method my credit card. My bank is not showing anything. Amazon is zero help trying to say it went back on a gift balance, which I have photo proof that both are incorrect. I tried to reach out to the seller and they were also zero help so I advise one not to buy this because it’s small and cheap looking too you can’t get your refund back.
