Ah, that's the regular ground strap one. If I'm gonna shell out that kind of money, it's gonna have to be really different than the Ruths - so recessed insulator/electrode and ground strap.

I still haven't heard a single argument with data to back it up to stop using Ruths. Y'all can run your fancy racing spark plugs, but I get a 4 pack of Ruths for 35 bucks and they have never given me a single complaint.

Maybe next they will release "APR Racing Oil" which is just rotella in a new jug.
They've sold Motul 300V for about 10 years now, which is definitely not just rotella in a new jug.

Tuners will always suggest a colder plug as the risk of fouling it is better than running too hot and preigniting/detonation. If you're street driving on a stock turbo I'm sure you'll never have a reason to complain about stock heat plugs.

Of course apr doesnt have their very own spark plug warehouse in china, guys. What is possible, however is that they do have a deal with ngk or whoever to make a specific spark plug spec that doesnt exist elsewhere, under a contract. Pretty common thing to do, and if this is the case it isnt a pandoras box to flame the vendor for it. I dont know if thats whats happening here but im guessing it is, like how garret mades the turbo apr sells that otherwise doesnt exist.

My car misfires a bit with ruths if i havent let the car warm up at least a couple minutes before carefully driving away. Its fine after a mile of driving. Do i need apr coils, spark plugs or both?
Both, definitely. And an EQT ground harness. Stat.

Yup, loved the Ruths while Stage 2, running the Vortex though they were a mess above 6600rpm. Just buy some densos from FCPeuro once, and get em swapped out for free every 10k miles.
