Keep in mind that there are two types of Water Pumps for my 2002 Tundra V8. One is made in Japan and the other made in USA. The Japan one costs way more and has a polished finish. I almost ordered the Japan model for cool factor, but instead ordered via Aisin on Big Gurrl (Ammzon) for half the price. So far so good after 2+ years and 10k miles.
I’ve also ordered just about every important electronic direct sourced part for my truck from Big Gurrll (aka Ammzon). See Heathers Reviews over there. She doesn’t make any money but likes helping people.
1) 8 Denso Ignition Coils
2) MAF Sensor by Hitachi
3) Denso O2 Sensors (all 4)
Order direct from the manufacturers store and not from Funshui Xi Parts and Such Store. If the price is too good there is a problem. Read the description. If it sounds like its Chinese interpretation, then pass as well. I think many fall into a paranoia trap an the internet is a resonation board for lackey mechanical people. If you are highly doubtful, then order through your Local Online Toyota Parts Programme. They have the best prices on just about everything, except the Timing Belt and Electronics (see 1-3 above).
Spark Plugs are best bought at Auto Zoned or Onoreiliys. Best $ deal there and its quality checked.
