Here’s a pic of the Halo Pro Sport Boost gauge next to my most favorite mod of all time, the Ultra-Gauge. I installed the boost gauge through the Cravenspeed throttle body spacer, the way to get the most accurate boost reading.
Here is the Cravenspeed throttle body spacer, or as I like to call it, the bloody-knuckled, curse-infusing hand-destroyer:
There are only a few of these out there – and they all work basically the same. It’s such a PITA to get the bottom bolts done/undone. Anyway, back in the day, people put spacers on the throttle body for power and performance, but on this car, you will notice no change. I bought the one from Madness Autoworks, as it was the cheapest. They all come with a plug and a nipple – the nipple is used to connect to meth injection or a boost gauge, which is why most use them on this car.
Using this method, you will get little to no oil coming in your boost line. Mine had a filter, but it’s completely clean, so far! This one is made very well, and connects securely, but they are all basically the same.
