Wonder what's next? Maybe having to thoroughly wipe your feet, painstakingly clean the interior of the windshield, and verbally wish your Jag a hearty good day before it will start up first thing in the morning....

I miss the cars of the 1960s more and more with each passing year....

You do realize that butt hp is vastly different from dyno hp.

And I welded bungs into the side and tapped them for the fogger nozzles, and theyre dirrectly over each port in the plenum.

It does give better filtration and performance, but youre not gonna feel the performance increase from even the most calibrated butt dyno, it just not enough. But you have to ask yourself, is the money worth it for synthetic oil? hipo tires, brakes, exhaust, heck if you look at the costs of a Jaguar, you can buy a couple other cars for the price. Ive never ever seen an issue with MAFS is the filter is maintained properly(not over oiled) you can also use dry ones as well. That being said, on the new Jaguars with DUAL air filters, we are seeing issues with cold start running and idle because the OEM filter are manufactured on different days. The filter media has a slightly different flow imbalance which is causing MAFS imbalances from side to side, so on these I wouldnt recommend. The fix is installing OEM in matched sets that have the same day of manufacture stamped on the sides. Otherwise I use K&N's in everything.
