About this product

Part #: 300-129

The Modular Mid–Rise intake utilizes the popular Holley LS1/LS2/LS6 cathedral port Mid–Rise 2 x 4 intake Manifold along with a purpose built plenum base Adapter and a Holley 92MM EFI plenum top which converts it into a Mid–Rise EFI intake manifold. With a max overall height of only 10.44in., the Mid–Rise Manifold is an excellent choice for street and performance street/strip applications with a powerband from 1,500–6,500 RPM and limited hood clearance. It's perfect for a blow–thru or turbocharged application. Being part of the Holley modular intake line means that this intake is not only available as a complete kit with intake, adapter, 92MM top and fuel rails, but all parts can also be purchased separately for a custom intake build. The plenum Adapter (PN 300–231) will accept all of the popular Holley Hi–Ram plenum tops as a foundation for custom induction systems.

1974 Chevrolet Luv

What made you choose this particular product?

I put a Holley drop-in fuel pump hanger into a fuel cell without baffling. This pre filter soaks up fuel, reducing fuel starvation.

Is this your first time buying from this brand? Did you consider other brands?

Love Holley products.

Was it easy to install? Any installation tips that will help others?

If you can change a fuel pump pre-filter, you can install this.

Yes it was, if you get stuck there are many videos on how to instal and tune these things.

Once you've had a chance to use the product, did it meet your expectations?

Exspensive but worth it.

What made you choose this particular product?

I am running a 200cc and can't afford a v8 but still want to be one of the cool kids

What were you trying to accomplish by adding this product?

more horsepower

Was it easy install? Any installation tips that will help others?

Not an easy install since you need an adapter that I ended up milling

Any additional comments?

don't do it and buy a 289

Jonny Mill

1935 Ford Pickup

What made you choose this particular product?

I had a Holley carb on the truck and wanted to stick with the brand since it was still working great. I just wanted to have the peace of mind that comes with EFI.

What were you trying to accomplish by adding this product?

Better MPG and Horsepower.

Was it easy install? Any installation tips that will help others?

It was easy to install. I took the truck to an exhaust shop to weld in the O2 bung but did everything else myself. The wiring and fuel return line were a lot easier than I was expecting.

Once you’ve had a chance to use the product, did it meet your expectations?

It exceeded my expectations.

Any additional comments?

I highly recommend this product to anyone wanting to keep a traditional look but have the benefits of EFI.
