In the next month or so I'm going to (hopefully) be getting my Vrs wagon in for a custom map, ridding myself of the SAI incorrect flow code while it's in. 

 

Before I go, I'd like to make sure the car is in best condition. Its never had a real problem on MOTs, no issues in the 2 years I've owned it. The major thing I'm seeing is to upgrade the coil packs and plugs to the red top/ R8 versions as future proofing. The car is just hitting 95k and I can't see they've ever been replaced so why not. 

 

I've seen an NGK model listed under part number U5014, are these the versions people fit? If so, who h plugs will be best suited to it? With any luck the car should make on or around 200hp. 

 

I've always had my cars serviced at a local garage so I've not fitted spark plugs myself before, will I need to gap them myself, and if so is there a recommended scale for these? 

 

Lastly, any other recommendations for things to fit/ change before a remap? I don't want massive power, just a new lease of life for an old engine. 

I've just recently gone through the exact same situation as yourself.

 

Had my car mapped while removing the codes for the sai.

 

I did some research and just went with some NGK equivalent standard coils that I ordered from autodoc.

 

And got some ngk iridium versions of the standard plugs NGKIFR6Q-G that I ordered through euro car parts about £5 each if I remember correctly.

 

I've been told you don't gap iridium plugs as it will damage the tips and defeat the point of fitting them in the first place, also your car is only having a "stage 1" as it's called map so no need to mess with the plugs, they come from NGK already to the correct spec.
