My RX8 also got pretty piss poor compression numbers. The only time it struggled with a start up was with literally the original 20 years old plugs it came with and I had to do multiple hot starts. It still started and carried on.
At around 120,000 KM plan for spark plugs. It's easy, especially if you get a 1/4" torque wrench and 14mm 1/4 deep well socket.
I bought a 19’ Premium at 17 it’s a great little car beat the shit out of it for 4 years straight and it runs amazing still. Handles well in the winter as long as you have clearance it’ll get you there in one piece. Regular maintenance along with trans fluid change, spark plugs, brakes, diff fluid change. I’d recommend a cpo premium . Great value.
I would recommend that if you get one do a full service fluid change on everything. Change the coolant, the trans fluid, diff fluid, oil (10w30 or 10w40, do NOT use the 5w20 reccomended). You'll also want to set aside $80-90 for new spark plugs, and upgrade the coil packs to LS coils from Bennet Built whenever you can. Coils need to be replaced about every 30k miles.
Use the AC Delco iridium original plugs. Many sites will only show the double platinum as a replacement but every time I've ever driven an engine with those in it, it pinged or idled rough and iridiums always fixed it.
Over the years I’ve found that the factory recommended spark plugs typically work best. There are exceptions, but my ‘95 5.7 recently got some plain Jane ACDelco plugs and it is running great.
I just put in regular AC Delco plugs and it runs great.
The new plug is AC Delco 41-156. Cannot tell any difference in my Gen 2 after replacing plugs. It ran fine before and did afterwards as well.
I had the same experience and ended up getting a code. Swapped them out back to AC Delco and never had an issue.
These look like knockoff acdelco plugs.
