Pics of it all connected and my MAP Sensor after running the engine w/o the OCC properly installed... runs better than ever now. While it was off the road I replaced and upgraded my plugs, did an oil change(5w 40), cleaned my throttle body and added a spacer, and of course dropped in the Injen intake. I also was fortunate enough to get a great deal on the Lap 3 uncle chip but that will wait until I do some more research....
Also if anyone buys the throttle body spacer from the K5 Optima store I highly recommend you buy your own bolts because the ones in the kit you need an Allen key to tighten and the two bolts in the front are seemingly too long about 1cm or so and as they thread they start to push against the intake manifold creating a gap.
Haha I'm not sure how to woohoo the kit but ya, my kit came with two 15mm fittings and one 9mm fitting and two 15mm check valves. The manufacturer told me the hose from the manifold is meant to be replaced with the 15mm one. I suggested to him to update his kit with two smaller fittings and re use the oem manifold hose because it may not be possible to replace that manifold hose without removing the manifold itself. He told me he has some customers that have re used it and offered to send me the fittings i would need to do so at no cost. I figured I'll give it one good try to get in there and get that hose replaced without taking off the intake manifold and if I cant I will just tale him up on his offer of sending me new fittings.
Here's his email,
"Hi Dain,
Thank you for contacting us for the feedback. We tested both and we had better results with a 15mm hose directly from the intake manifold.
For the 2015 optima you should be able to remove the OEM hose from the side of the intake manifold without removing the intake manifold.
I do have people set up as used the OEM hose but we recommend to replace the OEM hose.
Please see both photos attached with OEM and without OEM hose.
If you want to set up with the OEM hose. we can send the fitting at no extra cost to you
Hey, I’m having the same exact issue with this product… I had to also go through with removing that pcv house tucked underneath…it was a PITA. Anyway, install went smooth but then the CEL came on a couple days after outputting a high idle code. I see you said you removed the map sensor and cleaned it. Can you elaborate what that is and how you did that? Thank you! If anyone else has any ideas on what it could be let me know! I think it’s a vacuum leak since that what often leads to high idle. The manufacturer is supposed to be mailing me new check valves to hopefully fix it.
