Oil and Filter Change Procedure

Parts and supplies:

  • Approximately 8 litres of 0W-40 synthetic oil
  • Oil filter element kit: Acura part 15430-RSR-E01
  • Seven(7) Honda oil plug crush washers
  • Rags, shop towels, optional incontinence pads
  • Underbody clips: Acura part 91505-TY2-003 (if you break one during removal)


  • Oil filter wrench:  Acura part 07AAA-T6NA100 – I measured it and the internal diameter is 74mm, with 14 flutes, which is a common size so you might even have one already for another car.
  • 10mm, 17mm, and 22mm hex sockets
  • T30 torx bit
  • Slotted screwdriver, might also need a trim removal tool
  • Clip removal tool
  • Ratchets and extensions as necessary
  • Torque wrench(es) capable of measuring 7 lb-ft to 30 lb-ft
  • Pneumatic ratchet or cordless/corded drill highly recommended
  • Form-A-funnel (or designated Acura part 07AAZ-T6NA100)
  • Oil drain pan, 10L capacity
  • Oil dispensing container, 8L capacity (like this from Amazon Canada)


  1.  Remove passenger side engine cover, trunk carpet, and forward trunk trim.  To remove trunk trim clips, use slotted screwdriver to unscrew the trim clips.  DO NOT pull them out.  Sometimes they will not unscrew as they cannot engage the threads.  If this happens, use a trim removal tool to gently pull the clip while turning with the screwdriver.  This should allow them to engage the threads and be removed.

  1. Using a T30 Torx bit, remove the oil filter access panel.

  1. Optional: Drive the car to warm up the oil a bit.
  2. Remove the oil filler cap and raise the car.
  3. Using 10mm socket, T30 Torx, and clip removal tool, remove the engine underbody shield.  A pneumatic ratchet or cordless drill/bit driver really comes in handy here. Try not to break those damn plastic clips (part D in the diagram below):

  1. I removed the rear center metal panel in order to remove the splash shield (although in retrospect I could have just loosened the bolts).

  1. Using 17mm socket, remove drain plugs and drain the oil into the drain pan. There are a total of 7 drain plugs. Note that there is one plug that must be drained first (the one that drains the reservoir). The others can be drained afterward in any order. I drained and re-installed the plugs one at a time since my drain pan isn’t large enough to cover all seven. Also, make sure the old crush washers are removed. Some of them were stuck to the engine block on mine. When re-installing drain plug, use a new crush washer and tighten to 30 lb-ft:

  1. Double-check that all drain plugs are tightened to 30 lb-ft. Then lower the car.
  2. Remove the oil filter with filter wrench and 22mm socket. Use the Form-A-Funnel, Acura tool, or just a bunch of rags and incontinence pads to prevent oil drips into the trunk and engine bay.

  1. Replace the oil filter element and O-rings.

  1. Install new oil filter and tighten to 18 lb-ft.
  2. Fill oil dispenser with 6.5L of engine oil and pour into engine.

  1. Check for leaks under car and around oil filter. Install oil filler cap and start engine.  Either warm up the car in garage or go for a drive to warm up the oil.  (Basically, go through the oil level check routine).
  2. After checking oil level, add oil to reach the max mark on the dipstick. I found 1L was enough to reach the max mark.
  3. Raise car and check for oil leaks. Re-install the splash shield, tighten bolts to 7 lb-ft.
  4. Lower car. Re-install the filter access panel and tighten bolts to 7 lb-ft.  Re-install the trunk trim (push clips in to install; no need to use screwdriver), and engine cover.
  5. Reset Maintenance minder.
  6. Go for a drive! Or sit back and have a well-deserved beer. (But not both.)


Roof Console – Radar Detector 12V Wiring access

It is easy to find 12V access in the Roof Console.

Using the “Mirror Tap” product gives easy & very clean access to ignition controlled 12V.

My installation used “Mirror Tap” & “Blend mount” products. I did not have to run wiring along the roof liner and go into the fuse panel.

Roof console module access is:  Roof Console Module 61T6NP2

NSX Wiring diagrams are here:  NSX auto dim mirror wiring connector (1)

NSX mirror wiring is here:  NSX auto dim mirror wiring connector (1)

This photo shows the product info and the installation: 

Every picture tells a story…
Opened the roof console per the instructions above. (Note there is a small cutout in 2 places to CAREFULLY release the light bezels, with a SMALL screwdriver…)
Two bolts (10mm socket) release the module…
The Mirror connector is on the left with the harness end attached to the roof. I removed it, but you don’t need to. (use the mirror side wiring)
The Pin 1, 12V, “lt’s grn” changes to Red on mirror side connector.
The Gnd is pin3… so its Blk

(And yes, it must be NSX magic how 3 wires go to the 5 wire mirror 😉
I chased down the interior wiring… OK, look above for:
NSX auto dim mirror wiring connector (1).pdf
NSX interior lights wiring.pdf

Lots of room up there & easy to feed the Escort connector down the same mirror wire cover in the windshield… (I bought the Escort iX because everyone else bought all the others… A year later, not that impressed 😉

Both the Blend Mount and Mirror Tap make this very easy & clean… JUST REMEMBER TO GET THE 20′ CABLE Mirror Tap… My 15″ install is a little tight… AND the right connector option for your detector!

Note that I did try to find a place to use the suction cup mount that comes with the detector. I do not believe it can be put in the “shaded area so that the GPS receiver can see the sky thru the “shade”…

Also, since the NSX 12V is “switched” so you can leave the unit ‘Auto Off” off, and then it comes on and off with the car.

End of Story…
Mirror Tap is the perfect solution… no wiring; 1 piece of shrink tube; well designed product!
Be sure to order the 20″ version with correct connector for your unit, of course. I got a 15″ version & its length is ok, but more slack would be better.
There are 4 sizes of “inserts” & I used the 2nd smallest for “+” & “-” leads, into the back of the light green mirror plug.
Pin 1 is “+” RED wire & pin 3 is “-” Black…
Pretty much done.

Sidebar Note 1 re GPS reception: My Escort GPS does not seem to receive through the NSX Glass, but it is OK under the center “dotted” mirror section.
Sidebar Note 2 about Blend Mount
Its expensive but perfect for the NSX. They do not provide the magnet & expect you to use that part from the Escort mount you received… I believe this mount allows the GPS to “see” the sky better than through the suction cup.




How To Update Your Map – Acura Navigation Updates

The following vehicle comes with 10 years of complimentary map updates:

  • 2017-2018 Acura NSX

Your Dash will notify you if there is new SW available.

Your dealer should be able do this, but mine could not complete the task. My dealer tried but the corporate system security would not allow them to download an executable file, so they could not complete the process…

It’s easy to update your Navigation maps if you want to. I went home and followed the instructions and updated my Mapping.

Instruction tell you:

” To perform these updates you will need the following:
 16 GB USB drive
 High-speed Internet connection
 Up to 4 hours of time

(I found DL, & install time to be just a few minutes each. It does NOT take 4 hours! Probably 30-45 minutes running back and forth between your computer and the car with a “memory stick”… you can use either USB port. I’m sure my 2nd time will take 15 minutes…)

The following link will take you to the instructions to do it.


This is what my Nov 2017 updated SW shows:

Aftermarket Tire Options

Article contributed by ScienceofSpeed.

Pirelli Trofeo R

The 2017 Acura NSX is equipped with 245/35-19 and 305/30-20 tires. This is the ideal size for both factory wheels as well as wheels like the forged Titan 7 T-S5 from ScienceofSpeed.

Tires for 19/20″ wheels for the street:

The standard factory tire is the Continental ContiSportContact 5P. This tire has a 240 treadwear rating. New to the market and available in factory sizes is the new Pirelli P Zero PZ4 model with a 220 treadwear rating. Also just out from Michelin is the Pilot Sport 4S. This tire is the replacement for the popular Pilot Super Sport. The treadwear rating from Michelin is 300 – however, Michelin seems to always “over-rate” their treadwear – in comparison, this tire is likely more like a 200-240 treadwear from other manufacturers.

Tires for 19/20″ wheels for the track:

The factory optional tire is the Pirelli Trofeo R. This is a high-performance track & competition tire not ideally suited for the street in wet conditions where the tire will be more prone to hydroplaning. However, if you want the best for the track, this is an excellent choice.

Michelin Pilot Sport 4S

Tires for 20/21″ wheels:

The tire availability for wheels with a larger diameter than factory is somewhat limited at the moment. However, as 20″ and 21″ wheels become more popular from OEM manufacturers, more options will start to become available. For 20″/ 21″ wheels with factory width (8.5″ front, 11″ rear), the Pirelli P Zero is available. For wheels with wider widths (20×9.0 & 21×12-12.5) Pirelli P Zero (255/30-20 & 325/25-21) and Michelin Pilot Super Sport (265/30-20 & 325/30-21) are available. It should be noted that the rear tire from Michelin is 1.5″ larger in diameter than factory. Although this does not appear to create a problem with traction control – the tire can rub on the rear fender / bumper mounting point in the fender when the car is lowered. The customer that reported this has a suspension lowered by 24mm. At factory ride height this is likely not an issue.  If you’re a die-hard Michelin fan and don’t want to go with the Pirelli, our friends at TireRack report that the Michelin Sport 4S will be available in May 2018 in the Pirelli sizing (255/30-20 & 325/25-21).
