These are the perfect upgrade to your 392 Scat Pack, Hellcat, RT, Trackhawk, etc. Expected power gains range from 20-50 RWHP! Gains can vary, depending on other modifications done to the vehicle.

 

This will require your heads to be sent in for inspection and then CNC'd with new components installed. There are some cases where we have cores to use, but it is not always a guarantee. 

 

Turnaround time is about 3 weeks from time of receiving your heads.

Good Enough
This doesn't fit precisely into place. You can see in the photo that the pleats just end with no frame on the sides to seal to the body of the housing. You can wiggle the end pleat into place but there's nothing holding it there so I don't know how long it will stay there. Not a big deal for me, but if you live on a dirt road, there could be enough air bypassing the filter that you may get a dusty car sooner. Price was fine, but I won't buy this filter again.

love it.
This filter fits a 2008 Lexus RX400h perfectly and gives the fresh, clean air. I recommend it.
