Thanks for the pics.
What bolted on top of the 660 box, I see the inserts or something in the corners.
The 2 660s 99 and 00 i owned never had anything that bolted fitted onto the 4x threaded inserts,had a fine mesh screen on rear and side from memory,i believe this airbox on the early rallye 98-00 was generic with a 620 super comp/and a few of the other lc4 models,fairly sure the 690 rallye air box is generic with the 01-06 660 rallyes,looks the same,never cross/refed the part numbers....01-06 had a 39mm fcr the 690rr has a 41mm,my 690 has alot of induction noise...love it
