I have read lots of threads here with some opinions but I still cannot nail down a solid answer....
I have an 04 G and I am wanting to upgrade the plugs to high performance plugs and was hoping anyone can chime in:

  1. Is there a plug that is highly recommended above anything else for Gallardo's? I know NGK are good plugs but not sure for lambos? I don't care about price, I want best performance
  2. I would like to upgrade the coils as well if it has any benefit and am hoping for recomendations for those as well?

All thoughts are welcome!

Check out A.M. Sticky... good info there. Did Extreme Performance: Denso Iridium Racing IK01-24 plugs and OEM (High Performance): VW/Audi Coil Pack #07K905715F on 4 Gallardo, everyone noticed a difference after.

Copper Spark Plugs vs. Iridium and Platinum: Understand for Top Performance

"Many people come to the point where they are forced to change the spark plugs on their vehicle and face a difficult decision; copper spark plugs or those of another type? You can find spark plugs in a variety of different metal combinations, including aluminum spark plugs, iridium plugs, platinum and more. Copper core spark plugs are still the most commonly seen, however, and many people agree that they are the best. However, the advertising that accompanies the different types of spark plugs is potentially misleading, so it's important to recognize the real difference between the spark plugs in question. In order to do that, it's necessary to first learn about what the metal in the spark plug is used for.
Purpose of the Metal

The metal in a spark plug serves a single basic purpose: to channel the electric energy from the plug wire through the spark plug so that it can be forced to the engine block in the form of a spark. Therefore, any metal that conducts electricity at all could potentially be used for a spark plug. The metal should also not get too hot; one of the main problems with some metals is that they overheat quickly, causing the electric charge itself to be compromised and the spark plug to not operate as smoothly.
Copper Spark Plugs

Copper spark plugs are generally considered to have the best performance of any spark plug type. This is potentially different from what advertising companies suggest, but the other metals are, unfortunately, not as conductive in general as copper is. Platinum and iridium plugs are more likely to overheat, which causes damage to the plug components and can compromise the delivery of the spark to the engine block.
Platinum and Iridium Plugs

Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity. Platinum has good longevity and the worst performance. Iridium has good longevity and a performance that is decent, which is why iridium plugs tend to be more expensive than any other type. Still, the difference between these plugs in terms of overall quality is minimal, as there is a trade off for each.

Most copper plugs need to be changed every 20,000 miles or so. Platinum and iridium plugs can often go for twice that before they require changing, but the overall performance will not be as good and you may have to deal with overheating of the plugs. This is potentially not worth the added cost of both platinum and iridium spark plugs, although the decision will depend upon your preference."

Thanks for all the responses. I ended up getting plugs and coils from amazon:
Spark Plugs: Denso 5311 IK24 Iridium
Coils: Audi 07K905715G

Even though everyone suggested the Audi coils F version, I figured G version would be even better? Will it still fit properly in my 04?
