Can't tell from the picture, but if the hole for the air silencer tube is totally blocked off with rubber, it's the 1LE. The 1LE was available both with and without the hole for the blue elbow that the Opti air supply line connects to.
Looks like the bottom of the throttle body side was folded up, not fully connected to the TB, allowing dirty air to bypass the MAF sensor. Common error when reinstalling the elbow.SOLD - GONE TO A (VERY) GOOD HOME ! - 94 Formula A3+1: 381ci forged stroker - Callies Stealth, Oliver 5.85 billet rods, BME nitrous pistons / CNC LT4 heads / CC solid roller / TH400+GearVendors OD / 4.11 Strange 12-bolt / 300-shot N2O / Spohn Suspension / roll bar / MoTeC M48 Pro engine management system /a few other odds 'n ends.

Yeah it's totally blocked off. I believe I put it fully back on. Dang used cars and the secret upgrades. Previous owner didn't even remember stuff he put t on after 12yrs lol. Has TB airfoil also
. So other question is my 96 had a vent tube for the opti...does the 94's?

93/94 = unvented Opti = no vent line hole.
95-97 = vented Opti = vent line holeSOLD - GONE TO A (VERY) GOOD HOME ! - 94 Formula A3+1: 381ci forged stroker - Callies Stealth, Oliver 5.85 billet rods, BME nitrous pistons / CNC LT4 heads / CC solid roller / TH400+GearVendors OD / 4.11 Strange 12-bolt / 300-shot N2O / Spohn Suspension / roll bar / MoTeC M48 Pro engine management system /a few other odds 'n ends.
