guys, When is a good time to do plugs, wires, cap, rotor? My xterra has 70,000 miles and it is a 2003 supercharged 3.3L. Also what plugs do you guys recommend for the supercharged motor. thanks

Per Nissan, the recommended service time for a tune up is at 60K. Done during this service, plugs, wires, air filter, fuel filter, in cabin microfilter, and flush and fill on fluids (Transmission, etc), are taken care of.

The timing belt and water pump are rated for 105K miles. totally separate service.

I had a Frontier with the same motor/tranny combo that your X does, and I used only NGK plugs. I have also heard that the Denso plugs are good, but I have never used them.

For the Supercharged X, the NGK Plug should be the Laser Platinum. Part number is 2300 and designation is PFR5B-11. They range from about 8.00 each to about 12.99 each in price depending on where you go. I like NGK plug wires as well, but pretty much as long as you use 8mm plug wires, you are good to go.

For the fuel filter, and air filter, I like using the Purolator filters.

The timing belt and water pump are rated for 105K miles. totally separate service.

I have a 2000 X and I called my dealer to check on the Timing belt and water pump. The told me that Nissan was switching to Timing chains in 2000 and I may have one. If I had a chain it is not recommended that it be changed. The guys said by the time the chain is worn out so is your engine.

My point is you may have a timing chain.

Not to offend, but the 00-04 Frontier and teh 00-04 Xterra all have the 3.3L VG motor. Both Supercharged and naturally aspirated. All VG motors in the Maxima, 300ZX, Frontier, Xterra, I30, J30, etc used a timing belt. Once Nissan discontinued the VG series completely in 2005, then all Nissan vehicles were on a timing chain system.

wow thanks for the info, I can get the NGK plugs through my work but where can I buy NGK plug wires at? also I have a K&N air filter hooked into the snorkel but how hard is it to do the fuel filter and where is it at. I only ask these questions because I can't find a repair book for the 03 model. thanks

Ok, glad to help. there are a couple different vendors that you can order the wire set from. The part number for the wire set is NX104 and the stock number is 52020. There are online vendors such as ngk.com, and I believe NOPI. Your local Advance Auto should either carry them or be able to get them overnight. Don't know pricing on them.

A friend of mine swears by Nology wires for his Nissan truck, as well as the 240SX.

oh and I neglected to mention that the motor designation if you need it is:

VG33ER

The NA is VG33E

cool, can I trouble you to tell me any tricks to doing the fuel filter or is it pretty easy to do. thanks

I changed mine about 4 weeks ago. It was a piece of cake. Just remember which way the fuel flow through the filter. After you get the old one out. Let the fuel drain out of it and look at all the crap that was going to go into your engine.
