that's a boost controller or turbo timer (not sure which, too lazy to go back and check lol), it should be somewhere you can monitor it. You COULD put fogs in, but it would be a very tight fit with the intercooler, so I would say most likely not (I know for me it's already a tight fit and I do not have fogs). You would also have to swap out the hood, grille, fenders, and headlights to go along with the bumper for a 99-00 conversion. As for the pillar, I'm sure you could, yes... and I got mine from Glowshift when I got my gauges, but theres tons of other places that sell them as well.assuming i get this, i have some questions. 1. can i relocate that apexi computer? i dont like how it sits on the dash. 2. could i ever put fogs on that front end or swap it to a 99-00 bumber? if you notice there is a guage missing on the double piller.. could i get a triple pillar with that boost gauge? and where at? i appreciate the help. thanks. i look forward to start the addiction.
