You're running the stock rubber accordian tube. Don't take out your screen. You're still too turbulent until you replace that pipe with a smooth wall.

I don't think we have a tech reading on the TB.... Willwren should be able to point you in the wright direction though.. He too is also supercharged... I think the cleaning of the SC'* TB'* might be a bit diffrent from us NA'd people... Willwren.. Care to jump in here..
The SC is actually easier (we don't have the little support bracket going to the lower intake....the L27 and L36 have it to support the weight of the TB on the plastic upper intake). Remove the MAF sensor FIRST. Set it inside the car for safekeeping.

Disconnect the cruise and throttle cables. Disconnect the rest of the harnesses to the TB. Should only be the TPS? I'm not thinking too well here. Disconnect the TB bracket. 2 screws into the TB, and 2 on the exhaust heatshield. Remember where all these go. I like to put them right back when I pull them.

Now remove the 3 studs holding the TB to the SC. Remove the TB. Remove the Maf screen CAREFULLY. There'* a small retaining ring holding it in. A bent paperclip can help get the screen started. After you have it apart, use a toothbrush and INTAKE SAFE cleaner. Not carb cleaner. Scrup and brush really well, then flush it out very well. Let it drip dry for 30 minutes before reassembly. You don't want the cleaner getting on the MAF sensor.

Did I leave anything out?

Well, I removed my MAF, and opened my air box...Mine didn't have this "cone" that everyone is writing about...from the TB back..is just the stock accordion tube then my stock rear airbox cover w/ 1 round opening with NO obstructions...as is the front box side...just 1 round opening...I removed the additional plastic tubing that routed it to the front grille/headlight (stock)...

For the results so far...EXCELLENT for the $$$...can definitely feel the diff.
As for the near future...I may route flex duct from front of airbox to lower grille area...as I have read here...Sounds like an advantage ... sucking cooler air..

In far future I do intend to purchase intake pipe and K&N cone...

Can't seem to locate a K & N replacement for my stock airbox...or I would try that first...

All in All...I recommend the procedure...for anybody that'* ON THE FENCE..

Will...does this p/n provide a clean, tight fit in the stock '93 airbox??...I might "open the face" of my airbox a little more..if it does not seem be too risky (particles passing the filter)...thanks for the response...
