Wimped OUT! I already have 275's, sent back the new in box DDII's for some DD1's. After the TT box and boost elbow, I am very pleased. I figure about every 100K or so it can't hurt to change the injectors. How long can they really stay clean with injector cleaner?? Figured @ the 100K valve adjustment, I'll go with some new ones. Anyone want some 275's with about 90K on them REAL CHEAP? They work perfectly, I just gotta change something while I'm in there. . I have one problem now. The 28+ PSI boost is trying to suck the stock air box and cleaner through the turbo hose! I have NEVER seen the little yellow useage indicator on my airbox show before I did this mod. Now it sucks it right to 100% clogged reading with a new Fleet filter EVERY time a munch the pedal. I love it! BUT, I do not think I want the K&N setup, whats another filter that drops into the airbox? Lets not start the never ending K&N issue here, just thought I saw another maker that drops into the stock box. I need a filter that breathes better BUT still filters most dirt and dust. I live on a dirt road and drive it every day. I do not want K&N under my conditions. Suggestions?
