Massive 3.5” Intake for 4.2L S/C Jaguar. Condition is "New".
The 3.5” Banshee Screamer Intake replaces the stock intake tract from the throttle body to the Air-box, increasing efficiency over the cast upper plenum and plastic J-Pipe for a better flowing pathway for airflow and increased volume over the stock intake tract.
The bottleneck at the rear of the stock upper plenum and RR upper plenum prove to be restrictive as shown in dyno results. The RR upper plenum is a good upgrade but only delivers gains in the mid range of the powerband.
In testing, just replacing the upper plenum with a tubular design shows gains upwards of 18hp/20tq across the entire powerband with peak hp being increased by 12hp/10tq at 6100rpm. The entire 3.5” Intake SHOULD be good for 18-20 peak horsepower over a completely stock intake tract.
This intake has been fitted and tested on a 2004 Jaguar XJR with the 4.2L S/C engine and should* work with other Supercharged Jaguar vehicles with the AJV8.
These are made by hand, by me, and to order. Please be patient while I fabricate and package your item. :)
Please specify which color in notes.
*Claims made for fitment are theoretical and made as an educated guess based on engine bay similarities and seller claims no responsibility and guarantees fitment on x350/x358 Jaguar XJRs only. Other models likely will not have fitment issues but this item has not been test fitted to those vehicles by the manufacturer so measurements may be off very slightly and modification might be required.
