Nissan Skyline Air Flow Meter Replacement Parts

Yes, but only on variants fitted with the RB-series turbocharged engines — most notably the RB20DET, RB25DET, and RB26DETT found in the R32, R33, and R34 Skyline generations — which use a hot-wire mass air flow (MAF) sensor as part of their fuel management. Naturally aspirated RB-series variants also used an air flow meter in their fuel injection systems, so the part is broadly applicable across fuel-injected Skyline models. However, if your Skyline runs a carburetted engine it will not have one, and you should confirm your engine code before ordering.

The R33 and R34 Skylines share the RB25DET engine family, which means there is a reasonable chance of overlap, but the R34 generation introduced revised engine management across the 1998 boundary and ancillary mounting details may differ. Engine code is the most reliable guide here — check your V5 or run a VIN check to confirm your exact code — and then ask the breaker to match against your registration before buying. Never assume cross-generation fitment without that check.

Yes, this is one case where the variant genuinely matters, because the GT-R uses the twin-turbocharged RB26DETT while the GT-T uses the single-turbo RB25DET — these are different engines with different air flow meters that are not interchangeable. Trim level differences like interior spec or body styling are irrelevant to fitment, but the engine code difference between GT-R and GT-T is fundamental. Always confirm your engine code with the breaker and make clear which variant you have.

The R32 GT-S used the RB20DET and the GTS-4 used the RB20DET with four-wheel drive, while the GT-R used the RB26DETT — so fitment depends entirely on matching engine codes rather than trim names or drivetrain layout alone. An RB20DET air flow meter will not suit an RB26DETT or RB25DET application, regardless of what the badge says. Supply your engine code to the breaker and they can confirm whether a specific unit is suitable for your car.

This is something you should confirm with the breaker or a specialist rather than assume, as ECU pairing and immobiliser compatibility on Skyline models is not straightforward and varies by generation and market specification. What matters for sourcing the correct unit is matching the engine code first — an incorrectly specced sensor will not work regardless of coding. A breaker familiar with Skylines will be able to advise on whether the unit they have is likely to be plug-and-play or may need further attention.

The vast majority of Nissan Skylines in the UK are Japanese domestic market (JDM) grey imports, and the engine codes on these cars are the same as the JDM specification — so sourcing from a UK breaker who has dismantled another JDM Skyline is usually straightforward provided the engine codes match. Where it can get complicated is if your car has been modified with a different engine or upgraded management system, which is not uncommon on Skylines. Always quote your engine code to the breaker and mention any known modifications so they can advise correctly.
