Descrizione
Air is the first restriction every naturally aspirated engine meets. Before the camshaft, before the exhaust, before the tune, there is a throttle blade sitting in the path, and its diameter sets a ceiling the rest of the build has to live with. The Intake Port replaces a factory blade with a 92 mm billet opening machined from a single block of aluminium.
The body is CNC cut rather than cast, which matters twice. Machined walls stay consistent from unit to unit, so the flow you measure on one is the flow you get on the next. The blade and shaft are also located to tighter tolerances than a cast housing, which is the difference between an idle that settles and an idle that hunts after the swap. The cable driven linkage keeps the install familiar to anyone who has worked on an LS swap, and the listing includes the TPS and IAC hardware so you are not chasing sensors separately.
Buyers reach for this part in three situations. A project car with a cam and head work that has outgrown the factory blade. A truck build where low end response and clean idle matter more than peak numbers. A swap harness job where the intake manifold is already off and the extra half hour to fit a larger body is free. In each case the sensible expectation is the same: a 92 mm body supports power the factory unit restricts, provided the intake and the tune are able to use it.
The cheapest restriction to remove is the one already sitting in the air path.

Where It Fits
The Intake Port is fitted by three groups of builders. The first is the cam and head project, where the engine already flows more air than the factory body can pass and the blade is now the limiting item. The second is the truck and daily driver build, where the goal is a throttle that responds cleanly from idle rather than a number on a dyno sheet. The third is the swap job, where the intake is off anyway and fitting a larger body costs an extra thirty minutes of labour. All three share one requirement: the supporting parts have to match. A 92 mm body on a stock manifold with a stock tune will not add power by itself.
Frequently Asked Questions
Q: What is included with the throttle body?
The billet body itself plus the throttle position sensor and idle air control hardware shown in the listing images. Gaskets and intake manifold bolts are not part of the set, so plan for those separately.
Q: Which engines does it fit?
It is built for GM LS series engines with a four bolt intake manifold pattern, which covers the LS1, LS2, LS3, LS6 and related family members. Check the bolt pattern on your manifold before ordering.
Q: Is it drive by wire?
No. This is a cable driven body, so the pedal side needs a cable and bracket rather than an electronic pedal signal. That makes it a common choice for older chassis and swap builds.
Q: Do I need a tune afterwards?
Expect to recalibrate. Swapping the throttle body changes the airflow the engine control unit expects, and a tune or a relearn procedure is what keeps the idle and the fuel trims correct.
Q: How much power will it add?
That depends entirely on the rest of the build. A larger body removes a restriction; it does not create airflow the cylinder heads and intake cannot use. Gains show up when the intake and cam already flow more than the factory unit allowed.
Q: Will it work with a stock intake manifold?
The bolt pattern is the deciding factor. It fits four bolt LS style manifolds. On a stock manifold with a stock tune, treat it as preparation for later work rather than an immediate gain.
Q: Does the idle need adjusting?
Usually yes. The idle air control hardware is included for that reason, and many builders set a slightly higher base idle after the swap. Relearn the TPS position first, then adjust idle.
Q: Is the sensor included?
The throttle position sensor and idle air control hardware are included as listed. If you plan to reuse factory sensors, keep the originals on hand for comparison before you start.
Q: How long does installation take?
Two to three hours for someone who has done intake work before, longer if the manifold has to come off. Add an hour if you are chasing a new throttle cable bracket.
Q: Is this a genuine GM part?
No. It is an aftermarket replacement part produced by a third party supplier and is not affiliated with or endorsed by General Motors. It is built to fit the same mounting pattern.
