I just hit 30K miles. The book wants the spark plugs changed. Any better than the rest? What about the wires...are the stock ones good enough
thanks

 

denso iridium or ngk iridium are the best.

 

those available at autozone/napa/advance?

 

NGK is at Advanced, I wouldn't waste your money on platinum tips or the iridium. They last longer but for the price, you could have swapped out three sets of the standard ones, and new they don't perform any better. Best bang for the buck is the NGK V-power, P/N BKR5EYA. Just check them every oil change and replace when needed and you're good.

 

Forgot to add, we use individual coil packs on the block. it basically acts as a transformer to step up the voltage prior to the spark plug. Since our coil packs sit directly over the plug, there is no wire to replace. The connector on the end of the coil pack is only carrying 12V and relatively low current so insulation does not need to be thick like the high voltage plug wires on older cars. Oh, it's also not removeable without cutting the engine harness.

You can upgrade to aftermarket coil packs if you want, but they are hard to find and expensive. The stock ones will work just fine.

 

Word for word, I agree 100%. Well stated vettereddie! Plug change on the xB is so simple, I replace mine every year. Takes maybe 10 minutes.

 

GREAT info, Nothing like saving a little scratch!

Thanks

 

I just changed out my plugs too. Bought the Densos from Toyota.

 

NGK IRIDIUM IX BKR5EIX-11

Are the NGK pre gaped?? what should the gap be ??

Thanks.
Keith.

 

From my post above, they should be a gap of .044



John

 

Thanks John.


Keith.

 

disagree in my case I run denso iridium's plugs... I do 30,000 miles a year... I can get 3 years vs twice a year

 

No problem! This is for the XB not TC!


I noticed you have both.



John

 

Those are great plugs too.


John

 

actually, the iridium plug gap should be .044

 

Yep it is how mine are gapped

 

I think I said that already


Thx



John

 

so is it safe to say this can be used for the xA also ??


Thanks
Keith.

 

How come on NGK's website all the plugs available for the xA/xB are listed as having a .032 gap? Any advantage to going .044?
