Best spark plug and tap for stock tune?

my car is approaching 50k miles and I want to be proactive and change the plugs and coil packs. I drive the car hard, at tracks and canyons, so not sure if that matters. I also may get a tune down the line but not now.

Should I just get the two step colder plugs now? I keep hearing good things about the ngk 97506 plugs. Or just stick with oem?

Also, what two should I run?

Thanks!

Go with OEM, when you start tuning you may want to look at other plugs gapped to what your tuner recommends.

To mirror what everyone else has already said, keep the OEM plugs if not tuned.

Do the stock OEM plugs come pre-gapped?

If you tune the car, the NGK iridium plugs were awesome gapped between .018-.022, do the coils at the same time when you have everything already apart to save the effort. Bavarian Motorsport makes a great coil pack

Does the coils need to be replaced as well when replacing the OEM plugs? I'm planning on doing me plugs, can I still reuse the coils?

Spark plugs are every 3 oil changes or 30k miles. Coils don't have to be changed on that schedule

We like to change them @ 60K, especially if going to a Stage 2 tune shortly. Ignition system takes a beating on higher boost levels.

About to change my oil and plugs. I plan to tune and catless DP within the next 6 mos or so. Is it okay to run the NGK iridium pre-tune? Also, any particular coils I should change to? Just hit 70k miles.

Sure you can. Also, stick with OEM coils on replacement.
