Large Bore Individual Throttle Body Kit
The Rennen ITB Large Bore kit brings roller barrel individual throttle bodies to classic Porsche 3.6 to 4.0 engines with 3-stud heads. Each cylinder gets its own throttle barrel in place of the factory butterfly valve, so airflow is less restricted and throttle response is far more immediate.
The kit is ready to fit with no modifications needed, and every Rennen ITB by JSR is CNC machined and hard anodised for a durable, motorsport-grade finish.
Frequently asked
Does the Large Bore Individual Throttle Body Kit fit my 911 Carrera?
This listing is specific to the Porsche 911 Carrera (964). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.

Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
