Massachussets area - 4.2 XKR Air filter box temporarily needed
Hi guys,
I would like to develop a 3.5” MAF system for the 4.2 cars, and the company that can do this, requires the original air filter box. I don’t have one, and shipping it from the EU to the states would be very expensive.
So now I am hoping if anyone of you have a 4.2 air box (model year 2003-2006) from an XKR to borrow for a week or 2, form next week on.
This new MAF will be of benefit for anyone that has seriously modded their XKR and want to squeeze out the most of it. The original MAF has a 75mm ID iirc, and the new one is slightly smaller than 89mm, so allows more air.
Really hope that someone could help,
Thanks in advance,
Andre.

Hopefully they'll get rid of that accordion section, too. That has to screw with the laminar flow.
However, won't a larger cross section mess with the MAF sensor? The sensor works by heating up an element and measuring how much current it takes to keep the the element at a certain temperature. The faster the air moves the more current it takes. If the cross section is larger, the air will be moving more slowly for the same volume of air. The MAF sensor would detect that as less airflow and the ECU would then reduce the amount of fuel being injected, resulting in a lean-running engine.
I guess the designer could "pinch" a section of the intake where the MAF sensor is located. That would allow the MAF sensor to operate correctly, but it would cause a restriction at that point.

We need to original airbox to measure the exact voltages the original MAF will give for certain airflow, and that will then be mapped onto a new maf in the larger tube. So the voltage readings/airflow will remain the same.
It is needed in New Brookfield Massachusetts, and of course I will pay for the shipping.
