Senna Carbon Fibre Intake Manifold - McLaren 4.0L

A Carbon Fibre intake manifold for McLaren 4.0L engines.

The Senna Carbon Fiber Intake Manifold has been painstakingly designed by McLaren Racing to be the most efficient and power producing one available. Attention to every detail was accounted for when creating this high performance induction component. On looks alone, you might agree, it makes the perfect centerpiece for your McLaren’s engine bay. However, if you’re familiar with the Senna product line, you already understand that the aspiration has always been to offer you much more!

The Most Power Producing McLaren Intake Manifold On The Market

Unlike most aftermarket manifolds where gains are seen near the top of the power band and suffer near the bottom, the Senna Carbon Fiber manifold provides global performance. Compared to the stock cast aluminum intake manifold, the Senna manifold not only produced more HP and torque but it did so through the ENTIRE POWER BAND! From the moment your turbos spool up, the Senna intake manifold starts making more power and torque.  The best part is nothing is sacrificed in terms of response or power under the curve.

Larger, Perfectly Molded Carbon Fiber Plenum

Proper function of the plenum is extremely important to the performance of any intake manifold. In the case of the 4.0L McLaren engine, ther is one plenum – shared with both banks. Not only should it be sized for correct volume, it provides even more benefits when shaped in such a way that distributes charged air more evenly amongst each of the precisely machined CNC aluminum velocity stacks leading into the runners. The lightweight carbon fiber plenum is molded and tapered to channel charged air effectively – reducing turbulence and accelerating the delivery of charged air to the engine. By maintaining balance and sustaining maximum airflow velocity and pressure when needed, your McLaren benefits by outputting more horsepower!

The Difference Is In The Details

Each manifold is matched to its upper and lower running section to maintain the perfect flow of air from the throttle body to the cylinder heads. To achieve this, McLaren engineers called for very tight tolerances where the upper and lower sections adjoin. That wasn’t enough though. To perfectly align the upper and lower ports, they took it a step further and installed dowel locating pins to ensure there were no steps or protrusions that could cause unnecessary turbulence found on aftermarket manifolds.

Rigorously Tested To Last

We wanted to offer an intake manifold with the highest level of strength and reliability so we teamed up with an expert in the field.  Using aircraft grade epoxies and carbon fiber layering methods, this manifold would match the strength tolerances of key components used in the aerospace industry. We then cycle tested this manifold design 144,000 times from 0–50psi in a high heat environment in order to replicate over 20 years of operation by the average McLaren owner! In the end, a burst test was performed where the test manifold was subjected to over 150psi! No other manifold on the market has undergone such grueling tests!

New boost pipes and fuel purge lines are included!
