Yes mossy I have Koni Red's and I used Monroe Strut Mates with them..
If your paying out good money on Koni's a $100 more wont hurt..
Strut Mate
Too often a new strut or cartridge is fitted with the old original and damaged suspension travel limit bushing (compression bumper) and dust boot. The Monroe Strut Mate kit includes a high quality, soft entry urethane compression bumper, a new dust boot, retaining strap and fitting instructions.
