Picked up a Red 6 speed 2005 RX8 About 4 days ago in Minneapolis MN. Have switched out to 5w 30 Synthetic, removed Airbox "baffles" and put in K'N filter, added 25mm wheel spacers on all 4 corners, different shift ****, have been adding Mystic FD 2 cycle oil in gas tank, and have been cleaning everything. Coils were just replaced and new Falken tires were put on before I got it. Car has 50,333 miles on it and of all the "toy" cars I have owned, I find myself smiling a ton more in this one. Have been reading the forum for 3 weeks so I could get familiar with the car before I jumped.

Nice to be here and thanks for all the info you have already taught me!

 

How was your compression test ?

 

Nice car! Enjoy and welcome to the club!

[Now put those baffles back in the air box and throw that K&N filter in the trash.]

 

Was told it was done when coils/plugs were recently replaced. Was in the 115-120 psi range- not sure if that was cold or hot start- assuming cold. Car fires up well cold or hot starting, idles well, and pulls hard when I ask it to. Just going with past owners word with no reason to doubt that- yet!

 

Thanks.. the K&N was only about $9.00 more than the "standard" one so figured wth. Been running K&N in my bikes and cars for a while so have all the cleaning/oiling supplies to use up on the filters I truly didn't notice any difference with the baffles out but the stock filter was not pretty so any filter was a vast improvement.

 

Thorne310, welcome to the forum! Great to have you join us. Congrats on your RX8, the car looks perfect! May it provide unlimited fun and unhampered travel across all terrains for as long as you two are together.

 

As long as you know what you are getting into with K&N. To me, the oil and dirt in the intake is not worth the ~1HP gain at 8K. The stock airbox is actually very well designed, and most of the mods people do to "improve" it actually have the opposite effect.
