Hey,

Looking to install new plugs in my 09 FX 35 before a big road trip in a couple weeks (im still rocking the factory ones with 150k kilometers on this thing)

After doing some reading the Denso brand is where im heading - the only question is which model will i choose

Is anyone using the "Iridium TT Twin Tip" 4712 (im looking at rockauto) - or should i just buy the Denso 3442 model that is more common

Looking for feedback from someone who has used them before i take the plunge

Thanks

Use the same Denso ones that come on it. Factory plugs always work better
