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.

Customer Questions
Will an engine flush clean my pistons?
No, an engine flush is unlikely to clean the pistons.
How to replace engine pistons?
Replacing engine pistons involves removing the engine from the vehicle, disassembling it, removing the pistons, inspecting the engine components, installing the new pistons, reassembling the engine, and testing it. It's a complex process that should only be attempted by experienced mechanics.
When do engine pistons rings go bad?
Engine piston rings can go bad due to wear and tear, inadequate lubrication, overheating, manufacturing defects, or improper installation. Symptoms of failing piston rings include reduced engine power, increased oil consumption, and blue smoke from the exhaust. Regular maintenance and inspection can help identify potential issues.
Why do engine piston rings fail?
Engine piston rings can fail due to wear and tear, inadequate lubrication, overheating, manufacturing defects, or improper installation. Regular maintenance and inspection of the engine can help identify potential issues. Symptoms of failing piston rings include reduced engine power, increased oil consumption, and blue smoke from the exhaust.
Can you replace engine pistons rings without removing the engine?
Replacing engine piston rings without removing the engine is possible but not recommended due to the extensive disassembly required and the risk of damaging other engine components. A full rebuild or overhaul is generally more efficient and effective.
Are oil pump gears necessary?
Yes, oil pump gears are essential for maintaining proper engine lubrication in an internal combustion engine.
How do oil pumps work?
Oil pumps work by creating pressure to circulate engine oil throughout an internal combustion engine.
Where is the oil pump located?
The oil pump is typically located inside the engine's lower oil pan or sump.
Why do oil pump failures happen?
Oil pump failures can arise from wear, contamination, poor maintenance, and manufacturing defects, causing inadequate lubrication and potential engine damage.
