Leading evidence: 'Check codes, nada' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check codes, nada' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

replaced the plugs and coils, used the bigger BERU's

I used the old coil bolts to reattach the heat shields as they are longer than the original heat shield bolts, but are the same diameter and threading.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

03 C2 Coupe, 85K miles, bone stock engine, which of these coils and plugs would you choose? I want the coils to fit without any problems. I'm leaning toward the Bremi coil and the NGK Iridiums.
Please give some explanation about your choices.
Keep in mind I don't track the car and it's my daily driver. Needs to be reliable in the mud, blood, and the beer!
There's also a rennlist discount code somewhere.
There are updated coils that are thicker so they come with longer bolts. These are great coils.

For spark plugs, Bosch and NGK are good.

Nope. Fit the same. I did an install video on the whole process. This was my first time changing them and it was pretty painful. Not much room in there to work especially for Cylinder 1 and 4. I dropped the muffler on the passenger side side, but not on the driver's side. If your muffler bolts/nuts are in good shape it is worth it to take them off.

The funky pliers that are in the post above made reattaching the coil wires much easier. What you don't see is the end is bent @ ~40 degree angle.
I used the old coil bolts to reattach the heat shields as they are longer than the original heat shield bolts, but are the same diameter and threading.
UPDATE: AMCPILOT (my mechanic):
1. checked the codes, nada
2. checked the oil filter, absolutely clean
3. replaced the plugs and coils, used the bigger BERU's
4. checked the exhaust system extensively
5. put it all back together, sounds, runs good, no codes
Drove it to work this morning, ran great. Hads lots more low end power. I left it in D and didn't shift manually, didn't need to, lot's more torque.
I hope your guy put in the standard Bosch plugs with 4 electrodes. I put some iridium single wire center electrode plugs in my car, and the damn center electrode on one plug was fried in less than 10K miles. Created a misfire, so I replaced everything...new upgraded coils and new Bosch 4 prong spark plugs. Been great ever since.
Hello guys,
Is there any difference (besides the obvious physical ones) between the old coils and the new larger ones? Are the new ones better than the old ones?
Thanks in advance
Awesome! Great recommendations for next time. Thank you.
