LS1/2/6 HI-RAM IM, EFI, 92MM LS TB

Overview

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!  The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.  Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations  EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.  Cast aluminum construction.  Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

Works well
Size: 16 Ounce (Pack of 1), Style: SPF 50
Smells amazing! Doesn’t leave greasy finish. The spray goes on super smooth and cover a lot of area. Sad it isn’t reef friendly and new formula has more chemicals in it than it used to.

It Works!
Size: 16 Ounce (Pack of 1), Style: SPF 50
My favorite sunscreen. Smells incredible. Reminds me of the beach every time I use it. Which is daily. Summers are brutal in the south and I don’t get paid enough for a farmers tan. Alba has saved me. I’m hooked on it. Also the price isn’t horrible either. Sunscreen can be so dang expensive. You get your moneys worth.

Defective item
Size: 16 Ounce (Pack of 1), Style: SPF 50
I requested a refund or replacement as one of the two bottles that arrived. Has an issue with spraying. When I put it in the unlocked position, it does not spray I requested from the seller, but the seller wants to meet to provide proof and requesting me to upload a video. When I explained the defect, they told me to move it to unlocked position. I buy this sunscreen all the time for my kids so I’m aware of how to lock and unlock a sunscreen Unfortunately through buyer/seller messaging you’re unable to leave a video so I will unfortunately have to leave a review here. I hope the seller will resolve this defective item.
